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.

Why is a confirmatory test required for semen but not for blood?

Asked by Chris Kay almost 10 years ago

Wow I am sorry I somehow didn't answer this question!! In my experience we do a presumptive test for both and then send to DNA testing because they will confirm the presence of DNA in the quantitative step. We do have the OBTI test for human blood but there's no reason to do it u less we're in a huge hurry to confirm human blood.

Asked by lucresia about 9 years ago

I wasn't aware that there were theories other than: Do the right thing. Don't do the wrong thing.

Figuring out which is which isn't really that hard. Doing it might be, but it's usually not hard to figure out.

Hope that helps!

I don't know how to edit my question to fix the photo link. The pic must be seen in order to provide thoughts on mold & debris vs. decomposing carcass. Thanks http://i834.photobucket.com/albums/zz263/spikeyjax/Mobile%20Uploads/PicsArt_11-01-12.30.19.jpg

Sorry I went to the link but it just loaded forever and I coudn't view the picture.

UPDATE: Hey on a whim I tried the link again and could see the picture. Unfortunately I still couldn't make a guess as to what the pile is. Though in my opinion it looks too light-colored to be a decomposing animal.

What advice do you have for a person interested in your position?

Asked by Nate about 9 years ago

Take as many science courses as you can. Visit all the crime labs in your area, talk to people, and try to get an internship in one or more of them.
