What is the purpose of using unique evidence identification numbers rather than descriptive labels alone?

Under what circumstances may a supervisor authorize an exception to standard chain of custody documentation procedures?
Answer: In declared emergencies where immediate safety threats require rapid action, with documentation completed as soon as possible after

Which practice helps prevent cross-contamination when packaging multiple items from the same crime scene?
Answer: Packaging each item separately in its own labeled container
Each item must be individually packaged to prevent cross-contamination, which could compromise DNA or trace evidence analysis and complicate the chain of custody.
What role does the evidence log book serve in a properly maintained evidence room?
Answer: It provides a master record of all evidence received, stored, transferred, and disposed of in the facility
The evidence log book is the master record for the entire evidence facility, tracking all items received, stored, transferred, and disposed of to provide facility-wide accountability.
How long must chain of custody documentation typically be retained after a case is fully adjudicated?

Retention periods are governed by applicable statutes and agency policy, with serious felony documentation often retained permanently or for many years to support potential appeals.
When an evidence technician receives evidence from a first responder who did not properly package it, what should the technician do?
Answer: Accept the evidence, note the improper packaging in the chain of custody documentation, and repackage correctly
The technician should accept the evidence, thoroughly document the improper packaging as received, and then repackage it correctly, creating a transparent record of the packaging issue.
