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.

Have you ever been emotional with the cases you have worked on?

Asked by Denise_ot5 over 7 years ago

Once in a great while something will catch me when I’m not expecting it. But very rarely.

Are you able to tell if a person was unconscious just before death after examining the body? For example if someone hit their head and knocked themselves unconscious before they actually died?

Asked by TS over 7 years ago

I don't believe so (in fact I believe I address this question during an autopsy scene in my book Perish) but you'd have to ask a pathologist. Sorry I can't help.

I am writing a paper on the neuroses and role of sadistic behavior of female-targeting serial murderers. With your professional stance, I feel that your contribution would be helpful. Do you have information on this topic?

Asked by HG over 7 years ago

Sorry, but no. I’ve never been involved in the psychology of the suspects.Best of luck!

I am complaining about a civil attorney. He was supposed to send me some photographs. He sent an envelope, said the photographs are enclosed, but they were not. He claims he sent them, and I lost them. Can the envelope be examined for residue?

Asked by Tom over 7 years ago

Almost certainly, no. Unlike television, real forensic equipment is designed to test for certain things. For example the mass spectrometer in the toxicology department is set to test for illegal narcotics and not heavy metals such as arsenic. If arsenic is suspected, it could be detected with a different instrument or different parameters programmed into the same instrument. So I doubt there is any equipment that could be set up to detect microscopic amounts of photographic chemicals, if a photo would even shed any.

How long will latent prints last when ninhydrin is used?

Asked by Krissy almost 7 years ago

I'm not sure what you mean: a) how long after a print is left will ninhydrin still detect it, in which case I can say from my own experiment that there's little rhyme or reason to this, sometimes older prints develop better than newer ones or vice versa, or b) how long does a print developed with ninhydrin last, and the answer to that is that ninhydrin is a dark purple dye, so it is permanent, though it will continue to develop so that the entire page may eventually turn purple so we use a fixative chemical on the now-visible print so that will stop the ninhydrin from darkening the paper further. I hope that helps!

Hello
Please give me details like background, investigation, evidence etc. Of O.J Simpson murder case?

Asked by Hifz Ur Rehman over 6 years ago

Sorry, I wouldn't know anything more about it than anyone else. Try Google. Or watch the excellent miniseries, "American Crime Story: The Run For His Life." It was great.

A Man is found dead near rail track falling from a train. Can a forensic expert say whether he jumped or accidentally fell or pushed by somebody from train?

Asked by Maria Rose over 6 years ago

I see that on TV all the time but I have a hard time believing it. But I don't know personally. Sorry!
