Forensic Scientist

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.

Do you think if someone had all the training and experience plus is post certified do you think they would have a better or the same chance at getting a job a civilian can get? As well about advancements? I guess it could be like anything else the more the better. Right?

Asked by Terry almost 6 years ago

I'm not sure what you mean by post certified?

If you ask a cop why do all cops have short hair and the cop says something like “we cut it short so we don’t pull it all out” what does that mean?

Asked by Ryan about 5 years ago

It means that, like most people, they get tired of people asking them stupid questions.

is there any device in existance which can sense a possible forensic evidence and give you something to strat search with????

Asked by rekhab over 5 years ago

That depends on the kind of forensic evidence.

If there is animal blood and human blood mixed at a crime scene, how does that affect a DNA test? In other words, does animal blood contaminate human blood enough to confuse a DNA test? How has this technology advanced in the past 10 years?

Asked by Gorgonbunny over 4 years ago

That’s an excellent question, that unfortunately I can’t answer. We have the OBTI test that can confirm blood is human, but beyond that…I don’t know if there are alleles that both animals and humans share that might show up in the average DNA analysis. Even if animals have some alleles that are the same as humans, if those aren’t the alleles looked for in a DNA test, then it wouldn’t affect things. But if they are, then I don’t know if scientists have a way to distinguish them. Sorry I can’t be more help!

Hello Lisa, what is the dumbest case you ever worked?

Asked by Steven almost 5 years ago

Nothing's really 'dumb' since every case involves, a minimum, property loss or inconvenience. Criminals can be dumb...the best example I can think of was when a bunch of boys broke the glass in a door to get into a jewelry store, couldn't find much to take, then were hightailing it out of there as the alarm rang and one was trying to climb back out the broken window and not having much luck when his buddy barreled through the other door simply by pushing the push bar on it. The video was hilarious.

Hi Lisa! Besides taking science based classes, I also want to shadow some criminalists that I connected with on LinkedIn. Have you ever shadowed/had someone shadow you? What was it like?

Asked by Theresa over 4 years ago

Sure, I visited crime labs and the coroner’s office before I got my first forensics job—usually it was just a tour and answering questions though I got to sit in with a police class at the coroner’s and view an autopsy and hear some lectures. Then I would do the same when we had visiting students. Interns are here for a longer period. We usually have them do minor paperwork and tasks and they can observe our work with evidence, fingerprints, scenes, etc so we can explain what we’re doing and why. It’s a great experience. I think you’ll find people in forensics very friendly and helpful. Best of luck to you!

Do witnesses often test positive for GSR residue on their hands? How close would they need to be when the firearm is discharged?

Asked by Cat twigg almost 5 years ago

I couldn't tell you--I haven't personally done any studies of bystanders at a shooting. GSR analysis is usually testing for primer residue, which can escape from the gun when fired. So someone could have GSR on their hands if they handled a gun, if they touched a surface near to where a gun was fired, if they handled the gun after it was fired, etc. This is why, though they've stated this on television every day for fifty years, having gunshot residue on your hands doesn't prove you fired a gun. Not having gunshot residue on your hands doesn't prove you have not fired a gun. The particles are very tiny and easily dislodged. These are some of the reasons why most agencies don't do gunshot residue analysis any more. Hope that helps!
