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.

Does being a forensic scientist allow time to have a family of your own?

Asked by Sophie about 6 years ago

Yes, of course! You often have to be a little flexible in your schedule, but it's no more a problem than in any other job.

Can a body be in water and not have rigamortis?

Asked by Amanda Marsh over 7 years ago

As far as I know, water doesn’t change the process of rigor mortis. The temperature of the water may speed it up or slow it down, but the process would still occur.

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

Asked by Denise_ot5 about 7 years ago

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

How long will latent prints last when ninhydrin is used?

Asked by Krissy over 6 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!

Do you think Roger Stone is guilty or innocent or unsure?

Asked by JW about 6 years ago

Who’s Roger Stone?

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.

Hello! How easy is it to collect finger prints, scan them and identify a match (I imagine its very hard) but out of say 100 cases how many could actually be solved using fingerprint analysis?

Asked by Eliza over 6 years ago

Generally about a 6 to 10% identified rate is good. Many prints that are collected at scenes by officers are ‘not of value for comparison ‘ (smudges or only have a few ridges) and many that are good belong to the victim or their friends, family, employees etc.
