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 think that's what I'm doing most of the time when I answer questions on this site. If you look over the previous Q&As you'll probably see a lot of homework questions.

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!

It may depend on what you want to do. If you want to work crime scene, then you might be a more attractive candidate with all the hands-on practical work of a forensic science degree. But if you want to be a DNA analyst, then I’d go with biology. Best thing to do is call the labs where you might someday apply and ask them. Best of luck!

Do most poll staffers agree that the ballots are REALLY confusing?
That's an awfully broad question. What do you think are the physical and chemical properties? Blood has hemoglobin. Hair grows out of your head. Footprints are impressions in the dirt. I'm pretty sure you could write a good answer to this question yourself.

The job requirements are whatever the hiring agency says they are, so it could be anything from a high school diploma to a PhD in genetics. The only way to know is to call the department or check their website for job vacancies.

I don't believe so (in fact I believe I address this question during an autopsy scene in my book Perish) but you'd have to ask a pathologist. Sorry I can't help.
