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.
I’m not sure what you mean. Do you mean how does a forensic scientist advance in their career, or what scientific advancements have been made by forensic scientists?
Share Answer: 
That entirely depends on the requirements of the hiring agency. Since they’d probably require advanced schooling so hirees would wind up being older. It also might have to do with liability if the person would need to drive agency vehicles, etc.

That sounds odd, but were they looking for blood or semen stains in particular, or just the DNA of whoever wore it?
Share Answer: 
I’m not a pathologist, so I really wouldn’t know for sure, but I know decomposition can vary wildly depending on circumstances—whether the body is exposed or contained or wrapped; temperature and humidity are majorly important; and predators, insects, water, shade vs sun, all can affect matters. My best guess is yes, it’s possible.

I would think they’d have to get rubbed off. I don’t know how one could hold a knife tightly enough to stab someone without smudging all the prints on the grip. Guns, despite what you see on television, are terrible surfaces for prints, though I guess if you were very careful and maybe propped the butt on something, I suppose you could use it without grasping and smudging some areas, like the grip (if it were smooth, otherwise it likely wouldn’t retain any prints anyway) or a shiny, chromed barrel. A knife, maybe if it was big enough that you could grip only part of the handle and leave the prints on the other part undisturbed. Or maybe part of the blade if you didn’t stick it in the body all the way. But I would think it would be tough to do.
Hope that helps!

If the stain is still visible, then clearly the semen is still there, so I see no reason why it wouldn't still have DNA in it. There might be a mixture from swabbing up the skin cells as well as the stain.
Hope that helps!
