Description

BACKGROUND

With the escalation of firearms crime, there is a need for forensic analysis systems that assist in providing resolutions for criminal investigations in a timely manner. Particularly, in the United States, there exists the highest rate of civilian gun ownership per capita with respect to the rest of the world's population. According to the CDC, between 1999 and 2014 there have been 185,718 homicides from use of a firearm and 291,571 suicides using a firearm.

Criminal Investigators need the resources to solve each crime expeditiously. Fortunately, when a gun is made, the manufacturing equipment etches microscopic markings on components of the gun. These markings serve as fingerprints, which can be used to identify each gun. In particular, when the gun is fired, these markings are transferred to the bullet or cartridge case. These markings are also known as tool marks. For the current system of forensic evidence analysis associated with gun-related crimes and injuries, an investigator may need to send the forensic evidence, such as bullets and bullet shell casings to the National Integrated Ballistic Information Network (NIBIN) for processing. More particularly, when law enforcement investigates crimes in which firearms are used, ballistic imaging of such bullets and cartridge cases can be important in solving crime. NIBIN possesses a national database of digital images of spent bullets and cartridge cases that were found at crime scenes or test-fired from confiscated weapons. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) manages the system and provides the equipment to crime labs around the country. Ballistic imaging is used to convert the spent rounds into two- or three-dimensional digital images that are uploaded into NIBIN. The software on the server searches for possible matches with other rounds that have similar tool marks and thus may have been fired from the same gun. After a possible match, or “hit” is identified, the crime lab secures the actual spent rounds and compares them under a microscope to confirm the hit. Finally, the lab generates a hit report and sends information on the hit to investigators. With the report, law enforcement investigators can link crimes associated with the identified hits, which can help them to identify suspects. Investigators can also use the report to understand patterns of gun crime, such as gun sharing and trafficking.

Unfortunately, criminal investigators often routinely wait a considerable amount of time before they can make this analysis. Although a mobile NIBIN van can be on the location of a shooting or crime, it may be burdensome and costly to maintain the amount of vans necessary to service law enforcement agencies. In many cases, the evidence can be transported to a NIBIN facility by hand carry or other type of conveyance. Currently, the time that it takes for mailing the evidence, ballistic imaging, laboratory analysis, and report generation can be approximately 2-3 months or longer. Long delays mean that once a hit report is sent from the crime lab to law enforcement, it might be too late to aid a particular investigation. Further, the hits often do not contain geographical data, indicating the location where the cartridge was found. This may give the criminal an excessive amount of time to strategize his/her efforts to evade the criminal investigation, deterring a criminal investigation resolution.

It is within this context that the embodiments arise.

SUMMARY

Embodiments of a networked computer system for dynamic forensic data capture and analysis is provided. It should be appreciated that the present embodiment can be implemented in numerous ways, such as a process, an apparatus, a system, a device, or a method. Several inventive embodiments are described below.

In some embodiments, a computing system for dynamic forensic data capture and analysis is provided. The computing system may include a processor coupled to a memory to execute forensic analysis detection scheme using a forensic analysis agent of a client node; wherein, the processor is operable to receive a user request for a computer activity and sense image data associated with the forensic evidence. For example, the processor may capture image and video using a camera utility to capture each surface of a specimen of forensic evidence to detect a variety of striations including breech face marking, firing pin markings, ejection marking and the like. Further, the processor may be operable to capture the Geographical Point System (GPS) coordinates of forensic evidence location. The processor may also be operable to generate and send ballistic specimen data including images, video, GPS data and various other investigative data to a networked server. Further, the processor may be operable to generate ballistic imaging metadata from the ballistic specimen data at the networked server. For example, the processor may generate a three-dimensional mathematical model of the specimen from the captured image data, detecting one or more dimensions of the tool marks to form an associated set of metadata. Moreover, the processor may be operable to generate and send a hit report of the forensic evidence to the client node. In some embodiments, the processor may be operable to perform preliminary analysis on the captured imaging at the client node, wherein striation markings are detected within the captured image data using the past ballistic imaging data downloaded from the networked server and the sample striation image patterns stored within a database. The processor may be operable to mark the detected striations on the captured image data prior to send the marked image data within the ballistic specimen data to the networked server. Further the processor may be able to identify criminal patterns based upon the hit report at the client node and filter suspect data based upon these identified criminal patterns, along with a set of forensic policies. Accordingly, the processor may in response be able to identify potential material suspects based upon the filtered suspect data.

In some embodiments, a tangible, non-transitory, computer-readable media having instructions whereupon which, when executed by a processor, cause the processor to perform the forensic analysis and detection method described herein. The method may include capturing image data of a specimen of forensic evidence at a client node, along with the GPS coordinates of forensic evidence location, where the method controls the lighting and magnification of the specimen. The method may further include generating a ballistic specimen data packet, wherein the ballistic specimen data packet includes the captured images and GPS coordinates. The method may also include sending the ballistic specimen data packet to a networked server. In response, the method may include generating ballistic imaging metadata from the ballistic specimen data at the networked server. Using the ballistic imaging metadata, the method may include generating a hit report of best matching striation markings from a database of past forensic evidence. Next, the method may include sending the hit report having suspect data from the networked server to the client node, wherein the crime lab server verifies the hit report using actual forensic evidence. Further, the method may include identifying criminal patterns based upon the hit report at the client node and filtering suspect data based upon these identified criminal patterns. Using a set of forensic policies, the method may include identifying potential material suspects based upon the filtered suspect data.

In some embodiments, a forensic microscope assembly is provided. The forensic microscope assembly for a client node may include a cradle, wherein the cradle is operable to receive the client node having an image sensor, three-dimensional scanner, and GPS utility. For example, the cradle may include a base portion and a pair of side arms coupled to the base for securely holding the client node. Further, the forensic microscope assembly may include a lens assembly coupled to the cradle such that the lens assembly is positioned to optically align with the image sensor disposed in the client node when the client node is held by the cradle. For example, the lens assembly may include a magnifying lens selectably attached to an assembly housing. A coupling member may be included within the lens assembly for connecting the lens assembly to the cradle. The forensic microscope assembly may include a forensic evidence holding member coupled to the lens assembly, wherein the forensic evidence aligns with the image sensor through the lens assembly. For example, the forensic evidence holding member may include an evidence stabilizer with grasping members for holding the forensic evidence steady while the image is being captured. In some embodiments, the forensic evidence may be a bullet shell casing, wherein the shell casing is held by the grasping members, such that the breech face aligns with the image sensor of the client node. Particularly, the lens assembly having a magnifying lens can magnify the breech face markings, firing pin markings, and ejection markings of the shell casing for imaging, wherein the user can send the images for subsequent identification. Additionally, as detected by the GPS software application utility, the geographical location of the position where the shell casing was found can be sent along with the captured image for mapping the image with other images found within a national database of forensic evidence.

DETAILED DESCRIPTION

The following embodiments describe a system for dynamic forensic data capture and analysis, having a forensic microscope assembly. It can be appreciated by one skilled in the art, that the embodiments may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the embodiments.

The networked computer system for dynamic forensic data capture and analysis may include a processor coupled to a memory to execute forensic analysis detection scheme using a forensic analysis agent of a client node; wherein, the processor is operable to receive a user request for a computer activity and sense image data associated with the forensic evidence. For example, the processor may capture image and video contents of each surface of a specimen of forensic evidence to detect a variety of striations including breech face marking, firing pin markings, ejection marking and the like using a camera utility; wherein the processor can control the lighting and magnification setting of a forensic microscope assembly that stabilizes the forensic evidence for image capture. Further, the processor may be operable to capture the Geographical Point System (GPS) coordinates of forensic evidence location. The processor may also be operable to generate and send ballistic specimen data including images, video, GPS data and the like to a networked server. Further, the processor may be operable to generate ballistic imaging metadata from the ballistic specimen data at the networked server. For example, the processor may generate a three-dimensional mathematical model of the specimen from the captured image data, detecting one or more dimensions of the tool marks to form an associated set of metadata. Moreover, the processor may be operable to generate and send a hit report of the forensic evidence to the client node. In some embodiments, the processor may be operable to perform preliminary analysis on the captured imaging at the client node, wherein striation markings are detected within the captured image data using the past ballistic imaging data downloaded from the networked server and the sample striation image patterns stored within a database. The processor may be operable to mark the detected striations on the captured image data prior to sending the marked image data within the ballistic specimen data to the networked server. Further the processor may be able to identify criminal patterns based upon the hit report at the client node and filter suspect data based upon these identified criminal patterns, along with a set of forensic policies. Accordingly, the processor may in response be able to identify potential material suspects based upon the filtered suspect data.

The forensic microscope assembly for a client node in some embodiments may include a cradle, wherein the cradle is operable to receive the client node having an image sensor. For example, the cradle may include a base portion and a pair of side arms coupled to the base for securely holding the client node. Further, the forensic microscope assembly may include a lens assembly coupled to the cradle such that the lens assembly is positioned to optically align with the image sensor disposed within the client node when the client node is held by the cradle. For example, the lens assembly may include a magnifying lens selectably attached to an assembly housing. Another coupling member may be included within the lens assembly for connecting the lens assembly to the cradle. The forensic microscope assembly may include a forensic evidence holding member coupled to the lens assembly, wherein the forensic evidence aligns with the image sensor through the lens assembly. For example, the forensic evidence holding member may include an evidence stabilizer with one or more grasping members for holding the forensic evidence steady while the image is being captured. In some embodiments, the forensic evidence may be a bullet shell casing, wherein the shell casing is held by the one or more grasping members, such that the breech face of the shell casing aligns with the image sensor within the client node. Particularly, upon user request, the forensic detection analysis agent may control a range of magnification settings of the magnifying lens within the lens assembly in an effort to make breech face markings, firing pin markings, and ejection markings of the shell casing visible for imaging. The forensic detection analysis agent can also adjust the lighting upon user request; and thereby, send the captured images for subsequent analysis. Additionally, as detected by a GPS software application utility of the client node, the forensic detection analysis agent can retrieve the geographical location of the position where the shell casing was found can be sent along with the image for mapping the image with other images found within a forensic detection server having a database of forensic evidence.

Advantageously, criminal investigators may no longer have to wait weeks for delivery of the actual evidence to a forensic laboratory for analysis. The mobile forensic microscope assembly having a magnifier lens assembly, which couples to the client node, can capture striations and microscopic images on the breech face of a firearms cartridge. The images can be sent to a server having a forensic detection analysis module that uses particular algorithms to make comparisons of these images with other stored markings associated with other firearms. Using a database of striations associated with various crime gun, a search report can be generated that identifies criminal leads that criminal investigators can use in shooting investigations. Once the investigators know that a particular firearm fired bullets at certain locations, they can start tying multiple crimes to specific people.

Referring to FIG. 1A, a system diagram of networked forensic computing system having multiple client nodes coupled to a server to provide dynamic forensic detection and analysis, in accordance with some embodiments is shown. The system includes at least one client node 110a-n, a network 160, at least one forensic detection server 130a-n, and a plurality of secondary storage devices 142a-n, 144, and 146. Computing devices nodes 110a-n, with local data store 122 and secondary data store 124, are coupled by a network 160 to the forensic detection server 130a-n having its own forensic detection analysis module 136 and remote storage device 142a-n. Each client node 110a-n may include a forensic detection analysis agent 150, memory 114, a processor 112, camera 116, and local data store 122. In some embodiments, the client node may also include a GPS utility 118, and three-dimensional (3D) scanner 120, and a secondary data store 124. Examples of the client nodes 110a-n may include, but are not limited to, personal computers, laptops, PDAs, mobile phones, network appliances, and the like. In some embodiments, the forensic detection analysis agent 150 may serve as a device that communicates with the forensic detection server 130a-n to perform the method of dynamic forensic detection and analysis described more in detail below. In other embodiments, the forensic detection analysis module 136 within the forensic detection server 130a may communicate with each client node 110a-n and serve as the sole agent that performs the method of forensic detection and analysis described herein. The client nodes 110a-n, forensic detection server 130a, and the storage devices 142a-n may reside on the same local area network (LAN), or on different LANs that may be coupled together through the Internet, and may be separated by firewalls, routers, and/or other network devices. In one embodiment, client nodes 110a-n may couple to network 160 through a mobile communication network. In another embodiment, the client nodes 110a-n, forensic detection server 130a-n, and the storage devices 142a-n may reside on different networks. In some embodiments, the forensic detection server 130a-n may reside in a cloud network. Although not shown, in various embodiments, the client node 110a-n may be notebook computers, desktop computers, microprocessor-based or programmable consumer electronics, network appliances, mobile telephones, smart telephones, pagers, radio frequency (RF) devices, infrared (IR) devices, Personal Digital Assistants (PDAs), set-top boxes, cameras, integrated devices combining at least two of the preceding devices, and the like.

The forensic detection server 130a may comprise a processor 132, memory 134, and forensic detection analysis module 136. The forensic detection server 130a may be a NIBIN server or a crime lab server. In particular, the forensic detection analysis module 136 may comprise processing software instructions and/or hardware logic required for forensic detection and analysis according to the embodiments described herein. The forensic detection server 130a-n may provide remote cloud storage capabilities for detected patterns associated with forensic detection, digital images of spent bullets and cartridge cases that were found at crime scenes or test-fired from confiscated weapons, detected striation tool marks, and various types of criminal behaviors or policies associated with forensic detection, through the storage devices 142a-n coupled by network 140. Further, these may couple to one or more tape-out devices 146 or any other secondary data store 144. The forensic detection server 130a may also comprise a local data storage unit (not shown), which can be one or more centralized data repositories having mappings of respective associations between each ballistic imaging and metadata and its location within a remote storage devices 142a-n. The local data store may represent one or multiple data structures (databases, repositories, files, etc.) residing on one or more mass storage devices, such as magnetic or optical storage based disks, tapes or hard drives. This local data store may be an internal component of the forensic detection server 130a-n. The local data store also may couple externally to forensic detection server 130a-n, or remotely through a network. The forensic detection server 130a-n can communicate with the remote storage devices 142a-n over a public or private network. Although not shown, in various embodiments, the forensic detection server 130a-n may be a notebook computer, desktop computer, microprocessor-based or programmable consumer electronics, network appliance, mobile telephone, smart telephone, radio frequency (RF) device, infrared (IR) device, Personal Digital Assistant (PDA), set-top box, an integrated device combining at least two of the preceding devices, and the like.

The system may include remote data storage units and tape-out devices coupled by a network to client nodes 110a-n. As such, a database of criminal/forensic behavior and/or policies may be stored within the local data store (122), remote disks 142a-n, secondary data store (124, 144), or tape-outs devices 146. The database may include detected patterns, previously stored striation markings, digital images of spent bullets and cartridge cases that were found at crime scenes or test-fired from confiscated weapons, and various types of behaviors or policies associated with forensic detection. In some embodiments, the client node 110a may retrieve previous results relating to a specimen initially from a remote data store to a local data store 122. In other embodiments, the database of criminal behavioral characteristics may be stored locally on the client node 110a-n or the forensic detection server 130a-n.

In operation, the forensic detection analysis agent 150 may couple to the memory 114 and processor 112 to execute a forensic analysis detection scheme; wherein, the forensic detection analysis agent 150 is responsive to a user request for a computer activity and sense image data associated with the forensic evidence. For example, when requested by the user, the forensic detection analysis agent 150 will instruct the processor 112 to actuate the image sensor of the capture image and video contents using camera 116, wherein a two-dimensional image of each surface of a specimen of forensic evidence is captured to detect a variety of striations including breech face marking, firing pin markings, ejection marking and the like. Also upon user request, the forensic detection analysis agent 150 may control a range of magnification settings of a magnifying lens (not shown) within a forensic microscope assembly (described more in detail with reference to FIGS. 2-7) in an effort to make breech face markings, firing pin markings, and ejection markings of the shell casing visible for imaging. The forensic detection analysis agent 150 can also adjust the lighting upon user request. In the alternative, the processor 112 may capture three-dimensional image data of the specimen of forensic evidence using the three-dimensional scanner 120. Additionally, the processor 112 may be operable to capture the geographical point system (GPS) coordinates of forensic evidence location. The forensic detection analysis agent 150 may generate and send ballistic specimen data packet including images, video, GPS data, scanning data, and the like to one or more of the networked servers 130a-n. Other data associated with the forensic specimen may be captured and sent, such as an individual evidence number, officer address, caliber, type of crime, department, and the like. In response, the forensic detection analysis module 136 may generate ballistic imaging metadata from the ballistic specimen data at the networked server. For example, the forensic detection analysis module 136 in cooperation with processor 132 and memory 134 may generate a three-dimensional mathematical model of the specimen from the captured image data, detecting one or more dimensions of the tool marks to form an associated set of metadata. Moreover, the forensic detection analysis module 136 may generate and send a hit report of the forensic evidence to the client node. For example, the forensic detection analysis module 136 may detect one or more dimension measurements of one or more tool marks and identify an associated position of each tool mark on the specimen. The dimension measurements may include the number of tool marks; the width and depth of each tool mark; the angle and direction of each spiral impression within the specimen; and the like. The forensic detection analysis module 136 may compare the dimension measurement and the position to a second set of stored forensic evidence measurements. Further, forensic detection analysis module 136 may detect a best match within a predetermine range of the dimension measurement and position. As a result, the forensic detection analysis module 136 identify a forensic evidence specimen and a suspect associated with the detected best match and generate a list of each identified forensic evidence specimen and an associated suspect to form the hit report having suspect data. The hit report can be used to further an investigation. It may not be conclusive evidence for the indictment of a suspect.

In some embodiments, the forensic detection analysis agent 150 may perform a preliminary analysis on the captured imaging data at the client node 110a-n, wherein striation markings are detected within the captured image data using the past ballistic imaging data downloaded from the networked server 130a-n and sample striation image patterns stored within a local data store 122 (to be explained in further detail with reference to FIG. 1B). For example, the processor 112 as instructed by the forensic detection analysis agent 150 may convert the two dimensional images captured by camera 116 into a three-dimensional model of the forensic evidence to be stored in local data store 122 and/or 124, in some embodiments. In the alternative, the processor 112 may capture three-dimensional image data of the specimen of forensic evidence using the three-dimensional scanner 120, using the three-dimensional image data to generate a three-dimensional model. The forensic detection analysis agent 150 can mark the detected striations on the captured image data or three-dimensional model prior to sending the marked image data within the ballistic specimen data to the networked server. Further, the forensic detection analysis agent 150 may be able to identify criminal patterns based upon the hit report at the client node 110a-n and filter suspect data based upon these identified criminal patterns, along with a set of forensic policies stored within local data store 122 and/or 124. Accordingly, the forensic detection analysis agent 150 may in response be able to identify potential material suspects based upon the filtered suspect data.

Advantageously, the client node 110a-n can be a portable handheld device that can be utilized in remote locations, where ballistics matches can be generated in the field by investigators. Local databases associated with each networked server 130a-n can store data pertaining to the region of service. Furthermore, the system for dynamic forensic data capture and analysis described herein can drastically decrease the time it takes for evidence recovered at the crime scene to be evaluated by a NIBIN specialist. That is, evidence evaluation can occur in real-time, while the investigating agent is still on location. In addition, this forensic system can drastically limit chain of custody issues associated with transporting evidence. As such, the forensic evidence can be maintained by the investigating agent and placed directly in the evidence vault. Further, leads can be generated in real time, where the agent can use the hit report having suspect data during an interview of witnesses and/or suspects while he is still on location.

It is appreciated that the components of exemplary operating environment 100 are exemplary and more or fewer components may be present in various configurations. It is appreciated that operating environment may be part of a distributed computing environment, a cloud computing environment, a client server environment, and the like.

In other words, as would be apparent to one of ordinary skill in the art after reading this description, the various features and functionality described herein may be implemented in the forensic detection system using any arrangement components necessary to perform the dynamic forensic detection and analysis; and can be implemented in one or more separate or shared modules in various combinations and permutations.

Referring the FIG. 1B, block diagram showing the contents of a forensic detection analysis agent of FIG. 1A as a striation detection utility in some embodiments is shown. An exemplary embodiment of the forensic detection analysis agent 150 is shown. Forensic detection analysis agent 150 may include a detection manager 152 in cooperation with five differing databases, including one for network server data store 155, sample tool marking patterns data store 156, user data store 157, forensic policies data store 158, and ballistic specimen data store 159. The forensic detection analysis agent 150 may also include a transmitter/receiver 154 that couples to receive and transmit data from the camera utility 116, GPS utility 118, 3D scanner utility 120, and one or more of the network detection servers 130a-n. The forensic detection analysis agent 150 may also include an image capture controller 165 for controlling the light setting and magnification of the forensic microscope assembly (discussed in further detail with reference to FIG. 7).

In operation, the detection manager 152 may perform the functions of forensic detection and analysis. For example, the detection manager 152 may identify striation markings using previous forensic history data by accessing a database containing previously stored digital images of spent bullets and cartridge cases that were found at crime scenes or test-fired from confiscated weapons, wherein the data is downloaded from the forensic detection server 130a-n and stored in network server data store 155. The detection manager 152 may collect sample patterns of striation tool marks, including breech face marking, firing pin markings, ejection marking and the like. The collected sample patterns may be stored in the sample tool marking patterns data store 156. Additionally, the detection manager 152 may analyze the forensic specimen based upon user data of data store 157, wherein the location of the investigator, the type of department, specialty and skills are used to select a best match for identifying suspect data. Further, the detection manager 152 may identify suspect data based upon forensic policies stored in data store 158, wherein particular aspects of the type of crime are used to define the analysis performed. For example, forensic policies relating to homicide, suicide, terrorism, and the like may be stored in forensic policies data store 158. In particular, a terrorist attack or a homicide may have a higher priority ranking associated with it than a less lethal criminal activity, such as suicide, robbery, car-jacking, random shootings and the like. Forensic policies data store 158 may also store datasets as to a plurality of make and model information corresponding to various types of firearms and their associated ammunition. Forensic policies data store 158 may store other criminal investigative data, such as name of criminal investigator, street address of crime, the crime type, caliber of firearm used, number of shell casings available, and the like. Witness statements can be preserved in a case management system database (not shown). Additionally, the detection manager 152 may identify criminal patterns based upon hit reports downloaded from one or more of the forensic detection server 130a-n to network server data store 155. Ultimately, the detection manager 152 may store ballistic specimen data in ballistic specimen data store 159, which can also be used for preliminary analysis on the client node 110a-n prior to transmitting the same to a forensic detection server 130a-n.

As used herein, the term agent and module might describe a given unit of functionality that can be performed in accordance with one or more embodiments of the present invention. As used herein, an agent and/or a module might be implemented utilizing any form of hardware, software, or a combination thereof. For example, one or more processors, controllers, application specific integrated circuits (ASICs), programmable logic arrays (PLAs), programmable array logic (PALs) devices, complex programmable logic devices (CPLDs), field programmable gate arrays (FPGAs), logical components, software routines or other mechanisms might be implemented to make up a module.

Further, the forensic detection analysis agent 150 can actuate and adjust the light source 239 of the forensic holding member 230 to light the forensic evidence 238 in preparation for imaging. Although the wiring of the circuit to control the magnification and light setting is not shown, as can be appreciated by those skilled in the art these features can be implemented readily. In operation as noted above, once the images are captured, the forensic detection analysis agent 150 can send these images directly or indirectly to a networked server 130a-n, such as a NIBIN or Crime lab server for further forensic analysis. In some embodiments, the metadata associated with the client node 110a-n may be sent with these images. Additionally, as detected by the GPS software application utility 118 of the client node 110a, the forensic detection analysis agent 150 can detect the geographical location of the position where the forensic evidence 238 was found and send this data within the ballistic specimen data packet along with the captured images for mapping the image with other images found within any of the networked storage devices, such as the NIBIN national database of forensic evidence.

Referring to FIG. 8, a flow diagram of a method 500 of forensic evidence analysis in accordance with some embodiments is shown. The method may include capturing image data of a specimen of forensic evidence at a client node in an action 510. For example, the user can request the forensic detection analysis agent 150 to instruct the processor 112 to capture image and video contents using camera 116, wherein each surface of a specimen of forensic evidence is captured to detect a variety of striations including breech face marking, firing pin markings, ejection marking and the like. The method may also include capturing GPS coordinate data of the location associated with the specimen in an action 520. Further in an action 530, the method may include generating a ballistic specimen data packet, wherein the ballistic specimen data packet includes the captured image data and GPS coordinate data. For example, the forensic detection analysis agent 150 may generate ballistic specimen data including images, video, GPS data, scanning data, and the like. In an action 540, the method may also include sending the ballistic specimen data packet to a networked server, such as networked server 130a-n at NIBIN or a crime lab. Next, the method may include generating ballistic imaging metadata of one or more tool marks associated with the specimen from the ballistic specimen data packet at the networked server in an action 550. For example, the forensic detection analysis module 136 in cooperation with processor 132 and memory 134 may generate a three-dimensional mathematical model of the specimen from the captured image data, detecting one or more dimensions of the tool marks to form an associated set of metadata. The method may also include generating a hit report of forensic evidence having best matching measurements from the ballistic imaging metadata using a database of past forensic evidence in an action 560. For example, the forensic detection analysis module 136 may detect one or more dimension measurements of one or more tool marks and identify an associated position of each tool mark on the specimen. The forensic detection analysis module 136 may compare the dimension measurement and the position to a second set of stored forensic evidence measurements. Further, forensic detection analysis module 136 may detect a best match within a predetermine range of the dimension measurement and position. As a result, the forensic detection analysis module 136 identify a forensic evidence specimen and a suspect associated with the detected best match and generate a list of each identified forensic evidence specimen and an associated suspect to form the hit report having suspect data. In an action 570, the method may include sending the hit report having suspect data to the client node.

Referring to FIG. 9, a flow diagram of a method 511 of capturing the forensic evidence imaging data in accordance with some embodiments is shown. The method may include securing the forensic evidence in a forensic evidence holding member in an action 512. For example, when a criminal investigator arrives at the scene of a crime, the officer can retrieve the shell casings separated from the bullets of the firing arm. The officer can open and close the grasping members 236 around a shell casing to hold the shell casing securely in the evidence stabilizing unit 234. In an action 514, the method may include coupling the forensic evidence holding member to a lens assembly and the lens assembly to a base that cradles the client node. For example, the user can couple the evidence stabilizer unit 234 to the forensic evidence holding member 230; and subsequently coupling the forensic evidence holding member 230 to the lens assembly 220. Further, the user may couple the lens assembly 220 to the cradle 210 that supports the client node 110a having a camera 116, e.g., an image sensor, such that the image sensor optically aligns with the forensic evidence 238. Next, the method may include initiating the light source to light the surface of the forensic evidence in an action 515. For example, the user may turn ON the light source 39 to light the surface for the forensic evidence 238. Additionally, the method may include selecting the magnification setting and magnifying the image of the forensic evidence in an action 516. For example, the user may select whether the image should be magnified at a certain parameter corresponding to a 100-500× amplification. In an action 518, the method may include capturing image data of the forensic evidence using the image sensor. For example, the user may initiate image-capturing feature of built-in camera 116 of the client node 110a to take several images of the forensic evidence 238.
