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.

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!

can you tell the age of pharmaceuticals - specifically Ritalin/methylphenidate - like how many years ago it was made?

Asked by rogernono over 8 years ago

I'm sorry, I wouldn't have any idea. Do you mean dating the actual pills, or once they're in a person's system? If the former I think you'd have to ask a chemist, if the latter, a toxicologist. Sorry I can't help.

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.

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 about 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.

Will a dry blood stain on rocks, say the interior of a cave, appear red after at least a year or would the stain be darker or change because of the conditions within the cave?

Asked by MK about 9 years ago

It will turn a dark red brown once it's completely dry, and will stay that color so far as I know if conditions stay consistent. If it changes further it would probably just fade a bit.

What type of decisions do you make

How to best process or obtain a piece of evidence.

What are some of the difficult parts of this job

Asked by Angel over 8 years ago

Being 'on call' and knowing you can be interrupted at any moment of the day and have to go to a crime scene, even if it's the middle of the night or a holiday. I've also had to change vacations because I have to testify in a trial. I hate that.
