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 was the craziest case you have ever worked on?

Asked by john34 over 8 years ago

I haven’t worked any really crazy ones, and sorry but any semi crazy ones would take too long to explain.

As a forensic scientist, do you use the diameter of blood splatters as clues to how the crime happened?

Asked by Rylee almost 9 years ago

Yes, the arcsin of the width divided by the length of the stain will give you the angle of impact at which the blood struck the surface (usually a wall). The direction of the stains can be traced back to a point of convergence and from there the angles can be traced back to a distance from the wall, giving you the approximate point in space where the blow was struck.

Lisa thanks you for responding. Yes there are many variables in this but what Iam asking is : If you had to take a measure of amount of blood that was on human skin , how would you?

Asked by Rodger over 8 years ago

I'm sorry but I really don't know.

What is you opinion on the product rule used in DNA match probabilities and is this a reliable statistical method to employ when new DNA profiling multiplexes analyse STR markers within the same chromosome?

Asked by andres11 about 9 years ago

Sorry, but as I'm not a DNA analyst, I wouldn't have any idea.

whats a typical day in the life of a forensic scientist?

Asked by kenia about 9 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.

Is there a way to tell the person's weight from their skeleton? I know you can tell age, race, old injuries and so much more. Would you be able to tell that the bones belonged to a 400lb man?

Asked by Desiré over 9 years ago

That's an excellent question but you need an anthropologist to answer it. I'm afraid I don't know. Sorry!

I played a video game recently that had two murderers - separate murders - freeze their respective victims' bodies to throw off the time of death. Does that actually work? If so, how long does it take to unfreeze?

Asked by R-Mod over 8 years ago

Changing the ambient temperature either up or down and then changing it back will affect a pathologist's estimate of time of death because they usually take that into consideration. I couldn't guess how long it would take it to unfreeze, but at room temperature I would think several hours at a minimum.
