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.

Okay, i'll email you.

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 over 9 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.

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

Asked by rogernono almost 10 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.

What are some of the difficult parts of this job

Asked by Angel almost 10 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. 

Hi Lisa thx for the answer. My question is it OK to declare vagal inhibition without sending hyoid bone to forensic lab. My fathers hyoid bone was not sent to forensic lab but was only manually examined. We suspect foul play here.

Asked by Raja over 9 years ago

A forensic lab wouldn't examine a hyoid bone. That would be done at the autopsy by the pathologist. To the best of my knowledge there isn't anything else to examine, just whether it's broken or not, and as I said it doesn't conclusively prove anything one way or the other.Best of luck.

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?

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

Is it true that a females DNA can't be used to trace paternal male lines? How would I trace my fathers ethnicity with him gone and no brothers?

Asked by L.Randolph almost 10 years ago

I'm not a DNA expert, but I know that half the 23 chromosomes in a person''s nuclear DNA come from one parent and half from the other parent, so part of the father's DNA would have to be present in the child.

Mitochondrial DNA (which is a different substance entirely, a circular structure present in the cell's mitochondria, whereas nuclear DNA is a double helix present in the cell nucleus) is passed from mother to child without recombining, so only the mother's mitochondrial DNA is present in the child. We test for mitochondrial DNA when nuclear DNA isn't available, like when we only have cut hair or fingernails or old bone to work with.
