The chain of custody record must contain identifiers that describe the evidence at the time it was found, such as location and position, as well as other details consistent with your jurisdictional requirements. In addition, the record must contain information on who collected the evidence and verification that the evidence was packaged and appropriately sealed. Remember that the information contained in this record will be included in your comprehensive report. This report may be the basis for testimony in court proceedings.
