Using DNA in crime scene investigations

I’ve been working in forensics for a few years now, focusing heavily on DNA analysis. It’s fascinating how a single hair can change the course of an investigation. I’m curious how others approach evidence collection — especially when it comes to ensuring the integrity of biological samples at the scene?

It’s crucial to document the scene meticulously when collecting evidence, especially with biological samples; i’ve found that using a camera with time stamps can really help maintain the chain of custody. Have you encountered challenges with sample contamination during your analyses?
