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.
You will most likely need at least an associates degree in forensics or a natural science. How agile you need to be depends on what you're doing--if you're working in a lab, consistently on level ground, a disability would not be an issue. If you're doing crime scene work and you need to sometimes climb on top of roofs or into attics, out in fields, etc., then you need to be mobile. But nothing like police officers or rescue personnel.
Hope that helps!
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!
I”m a civilian employee so I’m not in the strict line of command as perhaps a police officer is, so I don’t really think in terms of ‘orders.’ If there’s a request of us that we feel could be detrimental to the forensic evidence, we’ll tell them that and discuss alternatives. If that wouldn’t work, I’d get my supervisor involved. If the detectives insist, then I’d probably do what they want (provided of course it wasn’t illegal) and if it makes the case unprosecutable, then that’s on them. So far the issue has never come up.
Not positively…as far as I know they could tell the blood type and gender, but of course not the positive ID of DNA. I don’t know when they started doing serological testing such as secreter status and PGM sub typing. Hope that helps!
