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.
The coroner's or medical examiners office, or find a college with an anthropology major and ask one of the professors.
I'm sorry, I wouldn't have any idea. You'd have to ask a pathologist.
I'm sorry, I"m sure I answered this question months ago, I don' t know why it didn't post. The answer is there's no way to guess, a doctor would have to look at it. If there's no tissue, DNA might possibly be obtained from bones or teeth.
It depends on the crime, but in general I guess you look for how the perpetrator got in, how they got out, and what they disturbed while they were there. Then I look for what we could get information from (such as surfaces that they had to touch that are smooth and glossy and might have prints, whether they left blood or bodily fluids behind that could be tested, whether they wrote something or used something that could point to their identity, etc.).

Is there or isn't there a cure for AIDS?I'm afraid I'll need some more details than that.
I'm very interested now in phone number 'spoofing' that the telephone scammers use to call us, but the technology is a little beyond my ken. Actually a lot beyond my ken. I have a co-worker who could explain it but we never have time.
I actually don't know how a DNA analyst tells human from animal DNA, but I don't think it's very difficult. We have an easy field test called Hexagon OBTI that can tell animal from human blood in a matter of minutes.
