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.

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.

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

Go to college and major in forensic science or one of the natural sciences. Best of luck!

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

Asked by Julie about 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.

Asked by Cheryl over 7 years ago

As I’m not a toxicologist, I’m afraid I’d have no idea. Sorry!

Hi Lisa, have you ever thought about going through the process of becoming a sworn officer?

Asked by Scott about 6 years ago

No, thank you. I would never want to be a cop--I don' t know how they do what they do. I would hate having to deal with stressed-out people all day long.

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.

Lisa, I'm a published author working on a novel. Woman was murdered and buried 20+ years ago. Can authorities 1) determine her identity and 2) Can they tell whether she was pregnant when she died? Thank you in advance!

Asked by Jack over 7 years ago

Answer to both is: maybe. If she was buried in the earth over 20 years, unless the ground was always frozen or so dry that she mummified, there will most likely be only skeletal remains left. So they might be able to establish identity from dental records, medical device implants (say a pacemaker or an artificial hip), or something left in the grave with her (like an ID card). I believe anthropologists can tell from the pelvic bone if someone has given birth, but not if pregnant at the time of death. However depending on how far along the baby is, they might have their own bones present so then it would be obvious. Best of luck!
