What is an important precaution when marking evidence to collect latently developed fingerprints?

When collecting latently developed fingerprints, it is crucial to avoid damaging potential fingerprints. Latent fingerprints can be very delicate and may be easily destroyed by improper handling or marking processes. Careful consideration needs to be taken to preserve the integrity of the evidence, as any damage could compromise its value and lead to issues in the investigation or court proceedings.

Marking the evidence accurately and without causing harm ensures that the latents remain intact for further analysis, which is essential for successful identification and evidence gathering. Maintaining the quality of the fingerprints aids forensic experts in making accurate assessments and comparisons, ultimately impacting the outcome of criminal cases.
