Forensic Scientist

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 made a cast of a boot I found in dirt. When it is dry and I collect it as evidence, what kind of bag do I put it into? A large paper bag, a plastic Ziploc bag, or another type of container?

Asked by Sam over 6 years ago

Large paper bag. Casting agents usually warm up so that might create moisture inside a plastic container or bag. A cardboard box might be good as well to give it enough support to keep it from cracking.

How can you prove a controlled substance that was collected from highway isn’t contaminated

Asked by Julie over 6 years ago

It depends on what you're talking about--was what contaminated with what? Lots of things can be contaminated with things without results being affected. Take blood, you can mix blood with paint or dirt or maybe oil or types of soap and that won't affect the DNA profile. If you mix it with bleach or other blood, it will. So if you had, say, heroin, and it gets mixed with fingerprint powder or cotton fibers, it's still going to test as heroin. If you mix it with cocaine, maybe it won't. (Controlled substances are not my field.) So 'contamination' is not a one-size fits-all word.

What is the best way to read the writing imprints left on paper towels or ziplocks without scientific equipment?

Asked by Amyleigh73 about 7 years ago

I would try oblique lighting—try laying the piece down as flat as possible and then hold a flashlight to the side so the light beam travels across the piece instead of down onto it. Adjust the light to where it’s the most helpful. With the ziploc bag you might also put a piece of dark paper inside it to increase the constraint. That’s all I can think of since I’m not an expert in questioned documents. Best of luck!

I am busy studying Forensic DNA and srtuggle with the following questions:
consequences of contamination collecting DNA

Your assistance would be appreciated.

Asked by Lindi Steyn about 7 years ago

Contamination may make it impossible to get a DNA profile, or the profile might show a mixture. It will not cause a profile to look like someone else's DNA. Or it may have no effect at all. It depends what is contaminated with what.

Do you feel that the junk science portrayed on TV makes it more difficult for you to give successful evidence in court?

Asked by Marcel almost 7 years ago

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."

I am currently a sophomore in highschool and I want to be a forensic pathologist/medical examiner. But I don’t know what classes I absolutely need to take in highschool or what to major in college. Could you give me advice please ?

Asked by Isabelle about 7 years ago

If you want to be a pathologist you will have to be a doctor, and will need to go to med school. So you are looking for a pre-med program. Best of luck!

I am applying for a grad. program that allows me to pursue a masters in forensic science and a PhD in Biochemistry. How would this compare to if I acquire a PhD in forensic science instead? Thank you.

Asked by Joe over 6 years ago

I'm sorry but I have absolutely no idea. You might call the labs at which you'd like to work and ask about the positions you'd like to get, and see what they suggest. They would know a lot more than I would.

Best of luck!
