Forensic Scientist

Cape Coral, FL

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.

This is for my forensics class. Was there a case that took you longer than expected, or was very easy to solve?

Asked by TERENCE L SMITH over 6 years ago

Wow, that's kind of hard, possibly because we in forensics don't 'solve' cases, the detective does. We provide them the information that hopefully solves or helps to solve the case. Some that took a surprisingly short time: we had a would-be rapist drop his wallet at the scene. I recently had a burglary/arson/car theft in which I had some decent fingerprints, but they didn't match anyone in our city database. The detective had no leads at all and no idea where the car was. Then as is routine I checked the prints against the neighboring city's database, and got a hit, they questioned the suspect and he confessed. In my small town we often have the killer waiting at the scene and telling us that they did it. However, after sitting in jail for a while they may decide they were justified, so the legal trial may not even begin until 2-3 years later. One that took longer: we had the brutal double murder of a woman and a young girl in 1989. Despite a copious investigation of every friend, acquaintance, fingerprint or hair involved, no leads. Then two years ago a man was arrested on a relatively minor charge and his DNA was searched and hit on the unsolved murder. Hope that helps!

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

Asked by Julie almost 7 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.

Can you extract DNA from human poop?

Asked by Jessica over 7 years ago

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

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

Asked by Amyleigh73 almost 8 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 currently a Forensic Science Major and have to complete an internship, would a wildlife rehab and education center be a good location for this?

Asked by Sosi over 7 years ago

I think that depends entirely on where you live or want to work. If you intend to apply for lab or crime scene work in a large city, then no. If you're going to work crime scene in a remote area with a lot of outdoor scenes and animal activity, then maybe yes. Regardless, an internship at your local forensic facility would be better. If that's not possible, at least call them and ask for their advice.

How many people do you think have committed a crime and came here for help desposing the body and everything else?

Asked by Randlel over 7 years ago

My guess would be 0.Mostly it’s just kids wanting me to answer their homework questions.

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 almost 8 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!
