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 again that is way too broad a question. Most forensic science is based on biology, physics and chemistry, so it's all 'natural' science.

I’m sorry, no. I don’t feel qualified to do that.
Share Answer: 
I believe it’s a presumptive test, so it would not be considered ‘conclusive’ evidence, only an indication that further test (like DNA) would be appropriate.
I have never used an orthotolidine test, unless that’s the reagent in the Hemastix test strips. We used those a great deal at the coroner’s office—they’re very handy, but can have false positives. Deciding what reagent to use will always be a function of ease of use, possibility of false positives and false negatives, expense and hazards (such as carcinogenic properties).
Best of luck!

That's called the 'CSI Effect' and it can be a problem for juries to have unrealistic expectations. One instructor described it as "Juries don't know as much as they think they know, but they really do know a lot more than they used to know."

Most people are cross-trained in more than one area. In smaller agencies people might have to wear a lot of hats.

I’ve never had someone ask for transcripts at an interview, and I think it would be a little unreasonable for them to expect you to have them with you without warning.It will be generally like any other interview. When they ask what experience you have in forensics be sure to mention specific tests and techniques you’ve done, like superglue, crime scene reconstruction, the AFIS system, etc.

I’m so sorry for your loss. My advice would be to use rubber gloves and take the items to a porch or some dry outside spot if it’s not going to rain for a while, or the garage or utility room if so. If you’re sensitive to smells you might use swimmers nose plugs or a bandana tied over your face. Spread the items out on a clean paper bag or newspaper (or wax paper if there’s some pieces of paper in his wallet you want to keep. Anything that can be wet, like car keys or plastic cards, dip or wash them in a container of water with some bleach in it, then let dry. Let all the stuff in the wallet dry if necessary, then keep what you want and discard the rest. Some of the smell will dissipate the longer its left to dry but if it’s something that can’t be soaked in bleach, you may never get a smell completely out, as far as I know. Best of luck.
