The present evidence markers can be made from paper or plastic card stock or any other suitable printable medium. The size and shape of the markers is flexible. Shape can be customized to reflect the logo or badge configuration of the law enforcement agency (LEA) involved. The most common shapes include rectangular, round, diamond, triangular but any geometric shape can be used.
Markers may be custom designed and printed by the LEA or supplier in any desired quantity. Holders and stands may be specifically designed and produced for use with the markers, or improvised from available materials.

An initial step in assembling a crime scene investigation kit using the present evidence markers is to print the evidence markers that will be part of the crime scene investigation kit. This entails first creating an electronic file containing the desired characteristics of the markers such as size, color, shape, and any desired graphic content. The file may utilize well-known software including Microsoft Word or Microsoft PowerPoint file. Alternatively, the evidence markers may be produced by custom software, capable of accepting parameters such as the format of the marker identifier (letter, number, alphanumeric) together with first and last values, pertaining to the range of identifier values (such as 1 to 1,000, A to ZZZZ, or A1-A50 to Z1-Z50). Whatever the choice of software, the output file may be printed to produce the markers on a suitable printing apparatus. Such software would preferably also be capable of outputting one or more additional files to: (1) replace missing markers, and/or (2) print additional markers having identifiers that begin where a prior set left off, in case it is realized that the existing set of markers is insufficient.
In addition, stands and holders may be produced for use with the present evidence marking set. The specific types and numbers of stands and holders may be selected based on the known or expected characteristics of a crime scene or may be a mix of types to provide a general-purpose kit for crime scenes that incorporate several types of evidence. The markers and any stands and holders may be packaged into an evidence kit for ready transport to a crime scene.
Once the crime scene kit is deployed to a crime scene, the use of each marker may be recorded; this may be done on paper. A checklist may be generated contemporaneously with use of the markers, reflecting the specific markers involved in sequential order, as well as a listing of the graphic content common to the markers, and/or a sample graphic representation of a marker. Alternatively, the markers can be scanned individually at the time of or after deployment; if after deployment, the markers can be scanned periodically in batches (such as 1-25, then 26-50 and so on), or after all have been deployed. The information on deployed markers can be reviewed and compared to any remaining markers in the evidence kit, as an integrity check to ensure that all markers are accounted for.
If the markers are scanned, they can be scanned in place after being placed at the crime scene so that the scan includes both the marker and the evidence being marked (shell casing, bullet hole, article of clothing, blood, etc.).
After use of the marking kit at the crime scene investigation is considered complete the markers may, depending on chain of custody policy, be (1) retained together, where practicable, with the associated evidence—for example, a shell casing and the associated marker may be placed in the same evidence container; (2) destroyed; or (3) retained for use in a later crime scene investigation.
The record of markers used at a crime scene (whether paper or electronic), may be used in connection with the electronic file that was used to print the markers in order to print a replacement set and restore the evidence kit to full capacity. For example, if an evidence kit is prepared containing markers 1-500, and the crime scene uses markers 1-348, the electronic file may be configured to re-print markers 1-348 in order to restore the evidence kit to full capacity. Thus, in one embodiment, an electronic file may be prepared and used to print a desired number of markers having selected graphic content. The markers may be combined with a set of holders and stands of different types to prepare an evidence kit. The evidence kit will be deployed at a crime scene, with each used marker being scanned to create a record of which particular markers from the kit were used. If there are not enough markers in the evidence kit, the electronic file can be used to produce additional markers that continue the sequence present in the existing markers. The record of used markers may be used to produce a new or revised electronic file that can then be used to print a replacement set of the markers used at the crime scene, restoring the evidence kit to full capacity.
Although the present crime scene evidence marking components and method have been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications disclosed herein. For example, the present evidence markers may be of any suitable material and color, and may present any desired information in alphabetic, numeric, alphanumeric, and/or graphic form. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present disclosure.
