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 over 8 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.

Can you test for how long dna evidence is present. Like if I cut myself on accident three days ago could you time stamp that without me telling you how long ago the accident happened.

Asked by PF about 8 years ago

No. There is no time stamp on DNA, so far as I know.

Would there be DNA left if someone used a forge and turned a murder weapon (say a knife) into something else, or maybe just folded the steel multiple times?

Asked by RDSBandit about 8 years ago

I'm fairly sure that the high temperatures used in melting metal would destroy any DNA.

how long does it take to become a forensic scientist?

Asked by ali over 8 years ago

If you look over previous answers, you'll see that it depends upon the requirements of where you want to work. My job requires only a high school diploma but gives extra points for college degrees, so we all have at least a BS. A larger lab might require a BS. If you're doing DNA work they might require a PhD. The only way to know for sure is to call a few places you might be interested in and ask what they require. Best of luck!

Hi,
I'm worried I wouldn't be able to handle seeing the bodies knowing what they went through. Like I read about children that are abducted murdered and dumped and it scares me. Have you investigated a child murder? How do you distance yourself?

Asked by Landon over 8 years ago

I've been involved with a number of child murders but in every case the child was killed by someone in their own family, usually a parent. In one case a 6 year old was shot by an acquaintance of his older brother's, but the 6 year old wasn't the target, simply an inconvenient witness. I've never worked one where the child was abducted. I don't have chilidren so it's actually easier for me than for people who do. To me it's largely the same as any other murder, though harder in some ways because the victim looks so vulnerable. You handle it because there's so much to be done and you have to do it right, so thinking about all that keeps you from thinking about the tragedy of this young life.

a car VW jetta traveling at 30 or 40 mph hits a 67" tall 160 pound woman how far will she be thrown.

Asked by Sarah about 8 years ago

I'm sorry but I have no idea. You'd have to ask an accident investigator.

Hello Ms. Black, I have two questions 1) can those with a past juvenile conviction enter the field of forensics 2) might you be able to put me in touch with a forensic scientist who would do a informational job interview with one of my students?

Asked by SLP over 8 years ago

Please see earlier answer about convicted felons. But as far as I know it would probably depend on the kind of crime, whether it was a misdemeanor or felony, etc. Many juvenile records can be sealed or expunged as well, so that process could be worth checking out.
