What is the first step in the chain of custody procedures for evidence analysis?

The first step in the chain of custody procedures for evidence analysis is indeed to contact the laboratory to review procedures. This step is essential because it ensures that the investigator understands the specific requirements and protocols necessary for preserving and handling the evidence. Different laboratories may have unique handling criteria, documentation requirements, and procedures for accepting evidence. By reaching out to the laboratory first, an investigator can confirm how to properly package, label, and transport the evidence to maintain its integrity and admissibility in any subsequent legal proceedings.

This proactive approach helps to mitigate the risk of contamination, loss, or misidentification, which could compromise the evidence and the investigation’s overall validity.
