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 sorry but you'd really have to ask a pathologist, this is not my area. I imagine it would depend a lot on the individual situation--the environment, temperature, humidity. Insect activity can be pretty accurate. But I believe that pinpointing to a few hours after someone has been dead for weeks only happens on TV.

From a fingerprint, no. From DNA, not age but they can probably make estimates that the sample likely belongs to a particular racial profile. They can also look for markers from the Y chromosome to determine gender. However I don't know if they necessarily see all these loci in every analysis. Usually in DNA testing you have samples from the crime scene, the victim and the suspect, and we want to know if this sample matches either the victim or the suspect, period. So they most likely don't test for the other factors unless requested. But I am not a DNA analyst so I could be wrong--they could be able to tell all sorts of things that they don't put in the reports because it's not relevent to our particular case.

I honestly have no idea, and suspect it would depend on where you are applying--whatever the hiring agency's policies are. I'll ask my boss and get back to you.
OKAY! I finally asked my supervisor about this, and unfortunately the news is not too encouraging. If you were found guilty of a felony, you might have a real problem getting a job with a law enforcement agency. But just because the crime was a felony doesn't necessarily mean that was your charge, you could been found guilty of first degree misdemeanor or some lesser charge, and that might not preclude you from employment. Also, smaller agencies might be willing to waive this exclusion especially with military experience. And this is only in the event that you were convicted. If you were simply charged with the crime but not convicted, then most likely it isn't a problem at all. The only way to know for sure is to ask a few of the places you'd be interested in working at and see what they say.

That's a tough one. I've had cops put tools back into pry marks to show that they fit and unload weapons to make them 'safe' (which is an okay idea under certain circumstances, but usually not). I did something really stupid just a few days ago--after we had painstakingly located some spent casings in thick grass, I put a marker down, took a picture, then took the marker and went back to my car to get an envelope for the casings. Doh! Luckily another CSI standing there hadn't taken her eyes off them. A good 15 years ago at my lab an old-school trace evidence person took the shorts from a decomposed body and washed them in order to read the tag info...I remember the look of horror on the cops' faces when I had to tell them that all the hair and fiber and other trace evidence had been washed down the drain. Happily it didn't matter, the victim's boyfriend was convicted anyway.

No, I have not. I don't really have any favorites about forensic anatomy in particular, though I borrow Postmortem by Koehler & Wecht from my co-worker often. I also liked the books by Dr. Michael Baden and Dr. Thomas Noguchi. My favorite forensics book is probably Colin Beavan's Fingerprints.

I can try. I'm not an anthropologist, but we do have a field guide here showing the skeletons of many mammals and birds. We used to have a lot of 'found bones' calls at my agency--the area had a great deal of construction going on in the area and the digging would often turn up bones.

It depends on how you define 'perfect'...if I can't tell the perpetrator has even been there then we wouldn't even know a crime has occurred, so I wouldn't know it was a perfect crime. If you mean 'perfect' in that the guy didn't leave any DNA or fingerprints that we found, sure, all the time. I've had plenty of burglaries in which it was apparent that a burglary occurred, but between humidity and surface conditions and what the perp had to touch in order to get the job done, I find no fingerprints at all (not even the people who live there). If you walk up and shoot someone (especially with a revolver, so no dropped casings) and walk away, you're not going to leave anything. Maybe a hair or a skin cell, but how would a CSI find that on a dirty street? Hence, a 'perfect' crime. Unless you get a parking ticket on the next block or a witness waiting for a pizza delivery happens to look out their window or there's an ATM camera you didn't know about.
