Forensic Scientist

Female, 49

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.

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.

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 over 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!

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

Asked by Amyleigh73 over 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!

What is the next step from secondary school in order to become a forensic scientist ?

Yes. I don’t know if it’s actually from the poop or from the skin cells sloughed off on it, but you can.

I'm studying about fingerprint patterns and phenotypic variations between parents and their kids. Which of the patterns are dominant/recessive? How can there be different patterns on each finger?

Asked by Liza over 7 years ago

Fingerprints develop randomly as a child is moving around in the womb before birth, so they are not dictated by genes. That said, there can sometimes be vague similarities among family members (like having radial loops, all arches, or whatever). There are three patterns, loops, whorls and arches, and you can easily have some of your fingers have loops and then a few have whorls, or they can be all one type, or any combination.
