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.
It will turn a dark red brown once it's completely dry, and will stay that color so far as I know if conditions stay consistent. If it changes further it would probably just fade a bit.

How to best process or obtain a piece of evidence.
I'm sorry, I wouldn't have any idea. Do you mean dating the actual pills, or once they're in a person's system? If the former I think you'd have to ask a chemist, if the latter, a toxicologist. Sorry I can't help.

I'm not a DNA expert, but I know that half the 23 chromosomes in a person''s nuclear DNA come from one parent and half from the other parent, so part of the father's DNA would have to be present in the child.
Mitochondrial DNA (which is a different substance entirely, a circular structure present in the cell's mitochondria, whereas nuclear DNA is a double helix present in the cell nucleus) is passed from mother to child without recombining, so only the mother's mitochondrial DNA is present in the child. We test for mitochondrial DNA when nuclear DNA isn't available, like when we only have cut hair or fingernails or old bone to work with.
If you look over previous answers, you'll see that it depends upon the requirements of where you want to work. My job requires only a high school diploma but gives extra points for college degrees, so we all have at least a BS. A larger lab might require a BS. If you're doing DNA work they might require a PhD. The only way to know for sure is to call a few places you might be interested in and ask what they require. Best of luck!
A forensic lab wouldn't examine a hyoid bone. That would be done at the autopsy by the pathologist. To the best of my knowledge there isn't anything else to examine, just whether it's broken or not, and as I said it doesn't conclusively prove anything one way or the other.Best of luck.
