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 old were you when you first became a forensic scientist?

Asked by Sara over 6 years ago

32. It was my second career, I majored in political science during my first round at college and was a personnel secretary for ten years first.

On a lot of TV shows, it's often said that water washed away dna evidence (ejaculate). Is it not possible for some to be left deep inside vagina? (Assuming there is ejaculate). Isn't it like taking a bath; water can't really get into vagina?

Asked by Leandra almost 7 years ago

Sorry, but I really don't know. You'd have to ask a pathologist. I imagine it might depend on how long after death the person was in the water.

How much methamphetamine would it take in a body that was submerged 4 two weeks, for an ME to consider it intoxicated? drowning with environmental hypothermia, contributory cause: methamphetamine intoxication

Asked by Lina N Lete over 6 years ago

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

Mrs. Black, I'm a freshmen in college and would like to know if you'd allow me to conduct an interview with yourself over email? This is for one of my classes since I am highly interested in becoming a csi.

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 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.

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 almost 7 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.
