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.

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.

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

Asked by Chris Kay over 9 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.

Is it possible for someone to shot themselves, first bulled lodge in the breast bone. throw up, pass out, come to and shot themselves a second time? Second bulled thru the heart and out the back ?

Asked by Linda about 9 years ago

Yes, quite possible. The breast bone blocked the bullet from hitting anything vital and so it wouldn't be fatal. We've had plenty of people shoot themselves in the head but the skull deflected the bullet enough that they either survived or had to fire a second shot.

Can a forensic examiner analyzing evidence distinguish between a latent fingerprint from a bare hand and those produced by someone wearing gloves?

Asked by kayla lions over 8 years ago

Sure, because fingerprints will have ridges and gloves will not.

Is there much if any room for mistakes in your job? How sever are the consequences? Can a forensic scientist redeem himself/herself after a mistake or is that the end of the line for him/her? How can mistakes be avoided? Much appreciate for your time

Asked by Ahmed Jordan almost 9 years ago

Like any other line of work, it all depends upon the mistake made, what effects it had, and how culpable you are. If it's a typo, just fix it and maybe make a note in the file. If you get someone killed, your boss will probably have to fire you. If it was an honest mistake, then you might get a note in your file. If you steal or invent evidence, you'll be fired and probably not work again.

My father was declared dead of vagal inhibition and cardiac arrest.. I have read that vagsl inhibition often caused by throttling and strangulation. How important it is to expertly examine the hyoid bone so rule out foul play

Asked by Raja over 9 years ago

I'm sorry to hear about your father. The hyoid would normally be observed during the course of an autopsy, but I have had pathologists tell me that people can be strangled without breaking the hyoid, and the hyoid can be broken due to other reasons,so it doesn't conclusively prove anything one way or the other.

whats the most challenging thing about your job?

Asked by kenia almost 9 years ago

Worrying that I might have missed a piece of evidence at a crime scene or in a lab process.
