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.

Why does the BLM not give a half a shit about the Australian American woman who was shot?

Asked by WE THE PEOPPE about 6 years ago

I am an expert in some areas of forensic science. I am not an expert in law, public safety policy or our political system.

Hi! I was wondering something about timing. Say a kidnapping takes place in a hotel room. How long is the room cordoned off? At what point is the evidence collected and taken away? When can the room be let again? (Working on a novel!)

Asked by Nico over 6 years ago

We’ll hold the scene as long as we need to get everything done, and that could be a day or two or three, but for a kidnapping it probably wouldn’t be more than a day, just enough to collect all the victim’s stuff, and collect fingerprints, hairs, fibers, anything that might belong to the kidnapper. We eventually get tired and want to go home (though we can go and come back, so long as it hasn’t been ‘released’) and the police department don’t really want to hold it longer then absolutely necessary, because they have a cop or two sitting there doing nothing but guarding the scene, and it takes them off the road. Hope that helps!

How anonymous are people really on the dark, deep, and even on the regular internet? What about websites where people talk about bad things they have, doing, or going to do without signing up or anything?

Asked by Dan over 6 years ago

I'm sorry, but I have no idea. I don't work in digital forensics.

Can a decades-old used latex condom buried with a body still have dna evidence in it that can be tested?

Asked by J.J. White about 6 years ago

If it were allowed to dry and kept dry, then it's possible, though the odds would be incredibly slim since the decomposition fluids from the body would most like overwhelm it. It's worth a try.

Can a hair test that came back false positive for alcohol be retested by another lab?

Asked by Joe over 6 years ago

I don’t see why not. But I wasn’t aware hair could be tested for alcohol, I thought it was only drugs and heavy metals.

Hi, so how do you get used to blood and gore?

Asked by Crazy about 6 years ago

You just do. Somehow you can either tolerate it or you can't, or you learn to cope with it. There are cops who can work homicide for thirty years and still have a weak stomach. They just don't let it keep them from doing their jobs.

I have not used cocaine in a year, why is my hair still testing positive for cocaine?

Asked by Terence J Donnelly almost 7 years ago

Hair is just dead cells, so once something is there, it stays there. Hair grows at about 1/2 inch per month, in general (mine, to my frustration, grows much more slowly). So if your hair is longer than say 6 inches, the cocaine will still be there. If your hair is much shorter, then I don’t know what’s happening.Hope that helps.
