I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
Possibly, I suppose. If they were swabbed thoroughly and the swabs picked up a few skin cells, then it would be within the realm of possibility.
Generally about a 6 to 10% identified rate is good. Many prints that are collected at scenes by officers are ‘not of value for comparison ‘ (smudges or only have a few ridges) and many that are good belong to the victim or their friends, family, employees etc.
They’re all shocking, in their way, But there hasn’t been one in particular that bowled me over.
I have no idea.

That's a pretty broad question. I can tell you that for both seminal stains and blood stains, the best way to package one is to let it dry, then place in a sterile paper envelope or bag. Never plastic! Then keep in a dry, cool environment.
Hope that helps.

I always loved mysteries and detection, but didn't want to be a cop.
