What is one of the key steps immediately following the collection of physical evidence?

One of the key steps immediately following the collection of physical evidence is to photograph the evidence. Proper documentation through photography serves multiple important purposes in criminal investigations.

Photographing the evidence ensures that there is a visual record of the scene and the evidence as it was found, which is crucial for both investigative and legal processes. This visual documentation can be critical during trials, as it allows juries and judges to see the evidence in its original context. Additionally, photographs can help preserve details that may not be clear later, given that physical evidence can be altered or contaminated once the crime scene is released.

Following the collection of evidence, taking photographs before any changes are made to the scene or the evidence itself helps uphold the integrity of the investigation. This step is essential in upholding the chain of custody and maintaining the evidential value of the items collected.
