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 is your typical day like?

Asked by Renee about 11 years ago

When I was at the coroner's office, a typical day would be examining victim's clothing from a homicide or suicide, typing blood samples and testing gunshot residue samples. Now at the police department, a typical day is spent in front of the computer putting in latent prints that the officers or I have lifted from items and searching for a match, or checking past searches of new people put in the system. Then I might go out to process a burglary scene.

Say that there was a crime scene with trama to the head and bleeding from the head and specialist forgot to take the temperature of that body, what is another way to determine the time of death?

Asked by bryce almost 11 years ago

Time of death is not determined as precisely as it is on television, I know, and they often use a number of factors to make an estimate such as when the person was seen last, mail piling up at the door, rigor mortis, lividity, etc. But honestly a pathologist could answer that question much more accurately than I could. They are the ones that determine TOD.

How long can GSR last on clothing or on a person?

Asked by Jailah about 11 years ago

On the shooter's hands, not very long. When we did GSR testing we would not do it if more than 4 hours had elapsed since the shooting. On clothing, it could depend on the type of material and how far away the item was--if it's a smooth fabric it would probably brush right off, but a more fuzzy type of thick material might get some particles stuck in it.

That was talking about primer residue. Gunpowder residue is bigger, heavier, and hot so it can fuse to some fibers or get 'stuck' to the item by the victim's blood.

Asked by jim about 10 years ago

i don't know. It would be worth a try.

Girl claims rape, boy says didn't happen. DNA came back inconclusive from rape kit except something in girls underwear they say is boys. How is that possible when nothing was discovered on girls body of boys, anywhere?

Asked by Momma about 10 years ago

Because human bodies are in constant flux. Cells slough off, fluids wash out other fluids, but a stain on a piece of cloth doesn't change.

Where do you see forensic science in the next ten years?

Asked by Mariana almost 11 years ago

DNA and fingerprints will still be the main forms of identification, but the focus on video, computers, social media and phone evidence will continue to expand. Anything that's not absolutely yes or no such as gunshot residue, fibers, maybe bitemarks will be discontinued.

Have you ever gotten emotionally attached to a case?

Asked by Jordan Hall about 10 years ago

No. There are cases and victims that I feel sorrier for than others, but nothing reaching the level that I would call emotionally involved. Everything is over by the time I get there, and then I don't usually see the victims or other parties again so there isn't an opportunity to bond.
