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.

Which, in your opinion, is the most effective in solving crime on a daily basis: DNA analysis, Fingerprint analysis or Luminol (or other) spray testing?

Asked by Eliza over 5 years ago

Luminal and dye stains just enhance or show you where things are, like blood or fingerprints. DNA analysis and fingerprint analysis are equally effective, so you use what you have. You might have DNA at a crime scene but no fingerprints, or vice versa. We don’t get a choice of what’s left at a crime scene, so we have to make the most of whatever is there. Given that, whatever is the most effective is whatever gives you information relevant to the crime. Say there’s a smear of the victim’s blood on the suspect’s shirt. The suspect tells police he found the body and tried to administer CPR. In that case, the DNA is very much there, but useless to solve the crime. If the suspect says he never met the victim and the same shirt is found in the suspect’s closet , then that’s very relevant to solving the crime.

What is the correct procedure to gather DNA doing a mouth swab and if it's not done correctly is it considered contaminated

Asked by Britni over 5 years ago

I'm sorry, I was sure I answered this long ago! Collecting buccal swabs is very easy--they come in a kit with everything necessary plus instructions for rubbing the swabs on the inside of the mouth and then packaging. Anyone could do it. I've never heard of a case where it was considered contaminated.

Can I ask you some questions for my novel? I need some things fact-checked. Probably too long to write on here.

HI! Did you ever regret pursuing your job? Also, can you be both, a forensic scientist and a CSI?

Asked by Fenis about 5 years ago

No, I've never regretted it. And your job title is whatever your agency says it is, so 'forensic scientist' and 'csi' can mean different things in different agencies, so you can certainly be both. the first implies you work mostly in the lab and the second implies you work mostly in the field, but depending on the size of the agency and any specialization you have, you might do both equally or they might be completely separate.

Would you be fired if you accidently messed something up and ruined a case? Even if it was a total mess up and no negligence was involved. What if there was?

Asked by Melvin over 5 years ago

That would depend entirely on what the mess up was and what it affected, and whether it was an honest mistake or the result of negligence or bias. For a serious mistake, yes, I'd probably be fired.

Can a hair test that came back false positive for alcohol be retested by another lab?

Asked by Joe over 5 years ago

I don’t see why not. But I wasn’t aware hair could be tested for alcohol, I thought it was only drugs and heavy metals.
