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.
Hi Cybill, I'm sorry I didn't get back to you sooner. I believe that they can use the inside of a tooth for DNA analysis, but of course if the tooth is loose they may not be able to determine which body it came from if there's more than one. I expect a dentist would need the teeth still in the jaw to compare with dental x-rays in order to make a comparison that way, but it may all depend on what work, if any, has been done to the tooth and how distinctive that work is. I'm not a DNA analyst (any more) or a dentist so I'm not 100% sure.

The people to ask would be the people hiring forensics personnel in LA county. All agencies (the police department, the sheriff's office, the medical examiner's office) should all have websites that post current job openings. If they don't have any current postings, then you can always call them and ask. That's the only way to know for sure. Best of luck!

I believe it’s a presumptive test, so it would not be considered ‘conclusive’ evidence, only an indication that further test (like DNA) would be appropriate.
I have never used an orthotolidine test, unless that’s the reagent in the Hemastix test strips. We used those a great deal at the coroner’s office—they’re very handy, but can have false positives. Deciding what reagent to use will always be a function of ease of use, possibility of false positives and false negatives, expense and hazards (such as carcinogenic properties).
Best of luck!

What's the meanest thing anyone's ever said to you?
They would most likely have rope fibers on their hands whether they hung themselves or were strangled. No, the furrow will usually get less deep and maybe disappear, depending on how tight the rope is, toward the spot where the knot is since it is usually higher up on the body as gravity pulls the body downward. As far as I know the location of the knot will depend on where it’s tied, if it’s slid around before suspension occurs, and the structure of the knot (if it slips or not). Being right or left handed shouldn’t make a difference therefore.

Many forensic chemistry departments only analyze possible drugs, so I would think it would be possible to find.
Share Answer: 
I'm sorry, but again that is way too broad a question. Most forensic science is based on biology, physics and chemistry, so it's all 'natural' science.
