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 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.

Is there a kind of gloves that doesn't leave gloveprints? Asking for a sort of detective story.

Asked by R-Mod almost 9 years ago

Sorry I didn't answer this before, I'm on the road. I've seen glove prints occasionally--a remarkable number of burglars don't bother to use them. But I've never compared the prints to a particular glove because by definition gloves are mass produced and therefore not unique like fingerprints. I've seen ones from cloth gloves, which will leave the knit pattern behind, or latex gloves which will sort of look like a group of random bubbles crammed together.

So unless the gloves and/or surface had some form of dirt or oil or other sort of substance that would make a print form, if both were completely spotless, there would be no gloveprints?

Asked by R-Mod almost 9 years ago

Probably not. Fingerprints are left usually because skin has oils and sweat, which of course gloves wouldn't have.

Please email me, I have tried to learn Forensics for my child's case, due to the Law lacking in Preserving and Safe Guarding evidence and lacking any witness statemnets although there was alit of people as potential witnesses?

Asked by Brandy about 9 years ago

Witness statements would be included with the officer's work, not the forensics unit. I'm sorry for your loss. Is there a victim's advocate at the police department that handled the crash that could help you? They could walk you through where to find all the information you want. You didn't include your email address.

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.

Can I interview you on this for a school project?

I am the one who asked the question about a right handed person shooting himself in the right temple with a 9 mm weapon.
This was my grandson and the answer is extremely important to me. I found him. if I give more info , can you give more detail?

Asked by Jeannie almost 9 years ago

I'm so sorry for your loss! However I doubt I could tell you anything more. I believe it's impossible to tell exactly what physics will take place. If you'd like, email me at Lisa-black@live.com with your details and I'll see if I can give you any opinions that might help.
