When should the search for latent prints at a crime scene begin?

The search for latent prints at a crime scene should begin at the point of entry because this area is often where the perpetrator first interacts with the scene. Entry points are typically where individuals touch surfaces while gaining access, making them prime locations for collecting latent prints. This strategic focus helps maximize the chances of finding usable evidence, as prints may still be present even if the perpetrator has moved deeper into the scene.

Starting at the point of entry enables investigators to thoroughly document the surroundings before any disturbances occur that might compromise the evidence. It also helps ensure that additional prints from the perpetrator or victims can be accounted for as the investigation unfolds. This approach is crucial for collecting accurate and reliable forensic evidence for analysis.
