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.

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

Asked by Steven over 3 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.

Hello, what would you do if your boss came in and asked you to test a vile of a COVID-19 vaccine for a possible crime but you did not know what it was however you did know it was a death investigation. What would you do? Thanks!!!

Asked by Mikey almost 4 years ago

My lab doesn’t have the ability to test vials of any time. We would send any liquid samples to the state lab.

What do you think is the minimum age for becoming a Forensic Scientist? Since it’s not (mostly) a sworn position can someone under 21 become one? What about under 18?

Asked by Samuel almost 4 years ago

That entirely depends on the requirements of the hiring agency. Since they’d probably require advanced schooling so hirees would wind up being older. It also might have to do with liability if the person would need to drive agency vehicles, etc.

Hello! I am currently taking classes such as Organic Chemistry and Physics, but not doing so well in them. I am worried that this may impact any grad programs in FS in that they will just not accept me altogether. Is there any advise you can give me?

Asked by Struggling Student over 3 years ago

I honestly have no idea, I never did a grad program. Are there any advisors at your target schools that you can ask? But I sympathize—I had the same problem with Organic Chemistry. I got A’s in General Chemistry, but I just never ‘got’ Organic. Best of luck to you!

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 almost 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.

Are you pretty much a unsworn detective? Do you do pretty much everything a detective does with the exception of arresting people or charging people?

Asked by Rae almost 4 years ago

No. I do lots of stuff detectives don’t do, like lab analysis, scene reconstruction, latent print comparison, etc. And they do tons of stuff I don’t do, like track down victims/witnesses/suspects and interview them, run criminal histories, request search warrants, and so on. So our jobs are really very different. We are there to provide the forensic support for the case, but forensic topics are only part of any case. Hope that helps!

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 over 3 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!
