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.

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 over 8 years ago

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

If the bar code if worn off of a computer and you are trying to figure out what the bar codes numbers were. How can you get the numbers? Cause where the bar code was before it was torn off. It left a lil bit of the code is visible.

Asked by Laray kirker over 8 years ago

I would try an alternate light source, UV or IR light or even white light with colored filters. That might make it more visible. Other than that, I don't know, sorry. You'd have to ask a document examiner, they might have more techniques for working with paper.

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 almost 9 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.

Would you be able to tell the difference between hair that was taken from a victim's brush (and planted at a crime scene) and hair that just naturally malted? For example, would hair from a hairbrush have more of a root than a malted hair??

Asked by Caroline almost 8 years ago

I don't know what malted means, but I suspect the answer is no. Just brushing hair can pull it out just as in a struggle.

How long would it take for a deceased body to drop below 32 degrees centigrade if they were in good health previously and the ambient temp was 17 degrees centigrade. Would the body be cold and blue to touch inside 2 hours?

Asked by Iain over 8 years ago

I'm sorry but I have no idea. That's a question for a pathologist. Sorry I couldn't help!

when i was in third grade i had a chemistry set- on day a relative gave me conc nitric acid; glycerin and some powdered magnesium - i almost got hurt -got lucky- do u think this person meant me harm- i've often wondered

Asked by markboutwell65@gmail.com over 8 years ago

Without knowing you or your relative, I really couldn't guess. Maybe they hoped you'd read the instructions first?

I am looking at becoming a DNA analyst working with hair, blood and gunshot residue samples, would it be better to get a degree in Forensic Science or a degree in Biology?

Asked by ssosiak1 almost 8 years ago

If you're going to be a DNA analyst, you will probably not be working with gunshot residue as well. DNA labs are tending to want their analysts to have a PhD in genetics and focus solely in that area, but it would be best if you called labs at which you might want to work and make sure. Best of luck.
