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 helps. But I know good homicide detectives who do it for years and still have a weak stomach and they do fine.

Hair is just dead cells, so once something is there, it stays there. Hair grows at about 1/2 inch per month, in general (mine, to my frustration, grows much more slowly). So if your hair is longer than say 6 inches, the cocaine will still be there. If your hair is much shorter, then I don’t know what’s happening.Hope that helps.

Honestly, I have no idea. I don't believe we've had any cases in my town yet, or perhaps I don't know because the police department wasn't involved.
Also, only the coroner's or medical examiner's office can declare a cause of death, or the attending doctor if they're under a doctor's care at the time. It's not up to the police department or any other government agency.

Wow, that's an extremely broad question. I don't know if the rates of crimes solved have been increased greatly--perhaps in some crimes like rape or murder but perhaps not in other crimes like burglary and theft. But certainly the biggest advances in forensics have been DNA and the connectedness of fingerprint databases. Less specific but perfectly valid analyses like pollen, soil, and other trace evidence examination have gone by the wayside. And digital analyses such as the downloading of cell phones and personal computers are helping solve crimes more and more, but then people didn't have cell phones or personal computers 40 years ago so I'm not sure that counts!
I hope that helps!

Do you think tablets are just a fad?

What's the the stupidest IT question you've every gotten?
Yes and no. Labs and units have expanded a lot in the past 10-20 years especially due to federal grants, but they're not as big as you see on TV. A small police department may do only fingerprints and send everything else to the state lab. A big city facility might take up an entire block or two and do everything from drug testing to paint and glass. As for skills, take as much science classes as you can and try to find programs with hands-on field work. Best of luck!

Yes.
Share Answer: 
I actually don't know. I haven't done DNA analysis in 20 years so I don't know all the details of what analysis can show. Sorry I can't be more help!
