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.

Which, in your opinion, is the most effective in solving crime on a daily basis: DNA analysis, Fingerprint analysis or Luminol (or other) spray testing?

Asked by Eliza almost 7 years ago

Luminal and dye stains just enhance or show you where things are, like blood or fingerprints. DNA analysis and fingerprint analysis are equally effective, so you use what you have. You might have DNA at a crime scene but no fingerprints, or vice versa. We don’t get a choice of what’s left at a crime scene, so we have to make the most of whatever is there. Given that, whatever is the most effective is whatever gives you information relevant to the crime. Say there’s a smear of the victim’s blood on the suspect’s shirt. The suspect tells police he found the body and tried to administer CPR. In that case, the DNA is very much there, but useless to solve the crime. If the suspect says he never met the victim and the same shirt is found in the suspect’s closet , then that’s very relevant to solving the crime.

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?

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

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.

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.

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 over 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.

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

Asked by Terence J Donnelly about 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.

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.
