Forensic Scientist

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.

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 3 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!

What is the outlook for employment? What is the level of education required? What do you like most about your career? What do you like least? What special skills are required? Are there any special physical demands?

Asked by Jessie over 3 years ago

Job requirements depend on the job. Requirements might range from a HS diploma to a PhD. Check the websites of forensic professional organizations (IAI, AAFS, pathology or other disciplines) for job vacancies. I like the variability of the days.I dislike the hours, which can be unpredictable, and require being ‘on call.’

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 3 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!

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 4 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!

Is there anyone special you worked with?

Asked by Jason over 3 years ago

Could you clarify that question? I'm not sure what mean.

What are some advancements from a forensic scientist?

Asked by GunKillerOdin over 3 years ago

I’m not sure what you mean. Do you mean how does a forensic scientist advance in their career, or what scientific advancements have been made by forensic scientists?

Another question is it true that there is no such thing as totally useless evidence? How much useless information has to be sifted through? I am sure this is more of a detective proble but I’m sure you have to deal with it too right?

Asked by Bobbie-Sue about 4 years ago

Yes, unlike what you see on television, evidence doesn’t necessarily ‘prove’ anything. It all depends on circumstances. If the victim’s blood is on the suspect’s shirt and he says he never met her, that’s vital evidence. If he found the body and tried to revive her, then it likely means nothing. Or bloodstains might tell me the victim was stabbed six inches away from the wall, but that doesn’t tell me who stabbed him. But if the perpetrator is caught and describes what happened, the bloodstains might corroborate or disprove his story. I hope that helps.
