What should occur once it is determined that a Crime Scene Unit (CSU) will process the scene?

Once it is determined that a Crime Scene Unit (CSU) will process the scene, it is crucial to wait for the CSU to arrive before processing any evidence. This is important because the CSU is specifically trained to handle crime scenes and employs standardized procedures to ensure that evidence is collected properly and preserved for forensic analysis. If evidence is disturbed or collected before the CSU arrives, it may lead to contamination or loss of critical information that could be vital for the investigation.

Processing evidence prematurely can compromise its integrity and could potentially render it inadmissible in court. The arrival of the CSU means that trained professionals will systematically document the scene, collect evidence, and ensure that all protocols are followed to maintain the chain of custody. This approach maximizes the chances of a successful investigation and prosecution by ensuring that evidence is handled correctly from the outset.
