What should be done when packaging firearms for evidence?

When packaging firearms for evidence, marking the serial number and not cleaning the weapon is crucial for maintaining the integrity and traceability of the evidence. Firearms should be handled with care to preserve any potential fingerprints, DNA, or other trace evidence that could provide critical information during an investigation.

Cleaning the firearm could destroy this evidence and potentially alter the condition of the firearm, which is necessary for forensic examination. Ensuring that the serial number is clearly marked helps in the identification and tracking of the firearm within the jurisdiction and the criminal justice system.

Additionally, submitting a loaded firearm as evidence is against protocol due to safety concerns, and all cartridges should be removed before packaging to avoid accidents and allow for thorough examination. Thus, the correct approach emphasizes the preservation of evidence and the safety of all involved in the process.
