Forensic Scientist

LIsa Black

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.

What can you tell me about death related to homicide, suicide and car fatalities.

Asked by Annette Davis about 6 years ago

That’s an exceedingly broad question that could take a stack of textbooks to answer.

How long does a body have to be exposed in warm temps before it starts to deteriorate?

Asked by LookingForJustice over 6 years ago

Bodies begin to deteriorate immediately, but the process might progress more slowly or less slowly depending on temperature, humidity, exposure or any medical conditions of the victim.

Asked by Lina N Lete over 6 years ago

I’m sorry but I have no idea. I’ve never worked in Toxicology.

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 over 6 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."

My son died recently and his keys were in his pocket. They gave me back the keys and wallet in a baggie and I need to clean them. I don't want to open the bag without knowing the best way to do it without the smell and such being overwhelming?

Asked by lmc over 6 years ago

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.

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

Asked by Julie about 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.
