In an investigation, when should latent fingerprints generally be developed?

Developing latent fingerprints is an important aspect of forensic investigations, and it is generally recommended to conduct this process after evidence collection has taken place. This is because developing latent fingerprints can potentially alter or damage other types of evidence present at the crime scene. By prioritizing the careful collection of all physical evidence first, investigators can minimize the risk of contaminating or compromising other findings that might be crucial to the case.

In combination with this, if fingerprints are developed before securing or collecting evidence, the process could inadvertently interfere with preserving the scene or collecting additional evidence in its original state. Therefore, conducting latent fingerprint development after the initial evidence collection ensures that investigators maintain the integrity of all evidence involved.
