Which of the following is not required when tagging or marking evidence?

When tagging or marking evidence, it is essential to accurately document certain key pieces of information to maintain the chain of custody and ensure the integrity of the evidence. The correct choice implies that the specific type of crime committed does not need to be included on the evidence tag.

Evidence tags typically include the name of the collecting officer, which helps identify who collected the evidence and ensures accountability. The date of collection is crucial for establishing the timeline of the investigation and for court purposes, as it helps to contextualize the evidence within the overall case timeline. The agency case number is fundamental for record-keeping and tracking the evidence within the specific investigation.

While understanding the nature of the crime is important for the investigation process, it is not a required piece of information to be documented directly on the evidence tag. Focus on the immediate identification and tracking of evidence takes precedence over detailing the specifics of the crime at this stage.
