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.

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 over 9 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.

My brother-in law, 24y.o. healthy male is with friends chat/laughing and laughs extra long, stops, head hangs down. Within minutes he passes away. At the time, drinking an energy drink and ate a peanut bar before. Post mortem, just scorched stomach??

Asked by Curious about 10 years ago

I'm sorry, I wouldn't have any idea. You'd have to ask a pathologist.

Can a forensic Scientist help me solve this quetsion? There was only one murderer.

Asked by Sujee Pundaisen over 9 years ago

I'm afraid I'll need some more details than that.

Approximately how many cases do you think you have solved in the last year?

Asked by Danielle over 9 years ago

I don't solve cases. Detectives solve cases. I suppose I actually 'solve' them when I get a fingerprint hit for a burglary where there would have been no other way to ever identify the burglar. That happens maybe 5-10 times a year. Otherwise forensic science is usually confirming or eliminating factors that are already suspected, and often provides information (say, what caliber of gun was used or where the burglar got into the house) that doesn't point to the identity of the criminal but adds details to the overall event.

I have read information regarding chemical enhancement techniques to view fingerprints in blood, however this got me thinking, does the use of fingerprint enhacement techniques such as powders suspension harm the confirmatory test for blood

Asked by Emily over 10 years ago

No. Almost all blood enhancement reagents will not destroy the blood for DNA testing. I don't think it would affect confirmatory tests either, but If we wanted to do a confirmatory test for blood such as phenolphthalein we would probably just do it on a spot where the marks were smeared or otherwise not useful as fingerprints.

Thank you so much for responding so fast. I really appreciate it. I have only a few more questions.

Are there any shows that you watch that are more accurate and show what forensic scientist really do?

Asked by Renee over 10 years ago

I don't really watch any except the ones on the ID channel, and those are mostly about the investigation. But when they do mention forensic evidence, they're accurate.

Is it possible to get someone else's DNA on underwear from a toilet seat... As in touching bowl when sitting?

Asked by Momma over 9 years ago

If there was semen on the toilet seat and it was still wet and sticky enough to stick to skin and then be transferred to underwear, then I suppose it would be possible.
