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.

how do finger[rints get on things, does our fingers leave fluids when we touch things, or we just leave a print on existing dust?

Asked by rekhab over 4 years ago

Sorry it took me so long to get back to you!

Yes, fingerprints are impressions made by the oil and sweat on our fingers. If a surface is very dusty, we take away dust on our fingers instead of leaving prints on the object. It will look like fingerprints should be there because there will be finger marks in the dust, but actually we just removed dust.

Hope that helps!

Hi, I’m writing a novel in which a tape-and-murder victim’s remains are found after ten or twenty years outdoors in rural New England. Could investigators find the perp’s dna at that point?

Asked by Laurel over 4 years ago

On the victim’s body? Most likely not because after that much time the victim would most likely be skeletal remains only, if buried and certainly if on the surface. If the body was in some kind of container, sealed, it might be completely decomposed, mummified or preserved, depending on circumstances. If the killer’s blood or semen got on some object that was with the body, it could conceivably survive if protected, but it would be very unlikely to yield a usable DNA profile.

Hope that helps!!

Also, is it possible to specifically detect that the DNA is from saliva and nothing else?

Asked by AJ over 4 years ago

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

Asked by rekhab over 4 years ago

That depends on the kind of forensic evidence.

What are the top 10 most fun/ interesting facts about your job?

Asked by Miki23 over 4 years ago

Wow, that’s a tough question! I’m not sure I could come up with ten.

Have you ever done a case where you did not think the person who did it deserved to be locked up?

How did you handle it?


If you have not. How would you react to that? If you’re asked to do a case but don’t agree the person should be arrested?

Asked by Mike about 4 years ago

My job isn't like TV--I'm not involved in every single aspect of the investigation. My job is to provide forensic support to the detectives, so in any given case I estimate I know perhaps 20% of the overall information relating to the crime. I don't know what witnesses, victims, suspects have said, what financial or phone records might show, etc. etc. The detectives would probably tell me if I asked, but I'm usually too busy with all the other cases to ask.

Who to arrest and who to prosecute is up to the detectives and the prosecutors. They don't ask my opinion, and in light of the first paragraph, I probably couldn't give them an informed one.
