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.

Where you ever shocked by a crime scene?

Asked by Denise_ot5 almost 6 years ago

They’re all shocking, in their way, But there hasn’t been one in particular that bowled me over.

I know they use interrogation techniques, polygraphs, and have experts who recognize truth and deception. But do and could someone use hypnosis?

Asked by DJ almost 5 years ago

Supposedly, but I don’t know of any cases personally.

I have not used cocaine in a year, why is my hair still testing positive for cocaine?

Asked by Terence J Donnelly over 5 years ago

Hair is just dead cells, so once something is there, it stays there. Hair grows at about 1/2 inch per month, in general (mine, to my frustration, grows much more slowly). So if your hair is longer than say 6 inches, the cocaine will still be there. If your hair is much shorter, then I don’t know what’s happening.Hope that helps.

How long will latent prints last when ninhydrin is used?

Asked by Krissy over 5 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!

What are some safety hazards, contamination / degradation hazards and how do u package SEMINAL STAINS A

Asked by Jayleen over 5 years ago

That's a pretty broad question. I can tell you that for both seminal stains and blood stains, the best way to package one is to let it dry, then place in a sterile paper envelope or bag. Never plastic! Then keep in a dry, cool environment.

Hope that helps.
