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: a) how long after a print is left will ninhydrin still detect it, in which case I can say from my own experiment that there's little rhyme or reason to this, sometimes older prints develop better than newer ones or vice versa, or b) how long does a print developed with ninhydrin last, and the answer to that is that ninhydrin is a dark purple dye, so it is permanent, though it will continue to develop so that the entire page may eventually turn purple so we use a fixative chemical on the now-visible print so that will stop the ninhydrin from darkening the paper further. I hope that helps!

They’re all shocking, in their way, But there hasn’t been one in particular that bowled me over.
Share Answer: 
I suppose that’s theoretically possible, but I wouldn’t think it likely. The saliva would sink into the paper of the money quickly, and then when swabbing the person’s skin you’d have to happen on the exact spot where that tiny bit of saliva transferred to.
I hope that helps!

Do you feel objectified when you're standing around in skimpy outfits?
Yes, of course! You often have to be a little flexible in your schedule, but it's no more a problem than in any other job.

It all depends on the circumstances of the death (fire victims can have a smoke smell, of course) but mostly the degree of decomposition. That's the only thing that makes a difference, otherwise everyone is the same.

Huh, that's a good question. I hope my books show what it's really like, except, of course, that my protagonist spends much more time out of the lab than in it, which is not at all realistic.
The non-fiction TV shows and books show reality, however, you have to remember that they're presenting cases that most investigators may come across once or twice in a lifetime.
Fiction shows, like "CSI" in which they have computerized databases of every substance in the world including toothpaste and wall paint, or ones in which female pathologists wear cocktail dresses to work. are definitely not realistic at all.
