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.
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.

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.

Again, titles and job requirements aren't uniform, so the only way to know is to call the crime labs in your area or whereever you might be interested in working and ask them. At the coroner's office we had to have at least a bachelor's in a natural science (this was before they had forensic science majors). At the police department where I am now, they only require a high school diploma but you get more points in the interviewing process for having a four year degree, so we all have one. You can also go on the websites for professional organizations such as the American Academy of Forensic Sciences and check out their job vacancy postings and see what the various positions require. Good luck.

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.

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.

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.

I apologize to your girlfriend on behalf of the law enforcement community. No one should ever be told that their crime is not 'a big enough deal.' Even if the responding person thinks that, and I'm not saying we don't sometimes, you would think they'd have better sense than to say so. Unfortunately you had a lazy cop who didn't want to get his hands dirty--or, truly, that could be an unofficial policy taught to rookies by other lazy cops who don't want to get their hands dirty. OR it could be the policy of the latent prints department who want to limit their caseload so they won't accept cases that had a claim less than X amount of dollars. So it's hard to know where it came from, but it's still wrong. Anyone who's burglarizing a condo is burglarizing plenty of other places as well and it would benefit everyone in town if they were caught. It would only take ten or fifteen minutes to throw some powder on at least the point of entry and any smooth and glossy surfaces the burglar had to have touched (bearing in mind that knocked over is not the same as touched) such as a mirrored medicine cabinet or a glossy lacquered jewelry box. Now if she's positive the perpetrator is her ne'er do well stepson who lives there (so that it is technically not burglary) or she realizes the burglary happened 3 weeks ago and she didn't check her jewelry until now or some such circumstances as that, or if the door had been left standing open and the only item disturbed is fabric-covered so it won't hold prints, I can understand not processing for prints, but they still should explain that. That said, burglaries are my LEAST favorite task at my job, but that's because I'm lazy and hate getting my hands dirty.
