Forensic Scientist

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.

Why are the questions on these pages so irrelevant and so many are repetitive as well as people just going on and on and on. Some people some how to way past the character limit. Sorry I know I’m kind of doing the same thing I’m just wondering

Asked by Paula almost 6 years ago

I didn't know there was a character limit. But yes, many people write 'how can I become a forensic scientist' without ever checking past questions to see that that has been asked 20 times. And I think others are trying to goad me into saying something non-PC. Apparently too many people have too much time on their hands.

What has been discovered or invented by you or other people who work in the field of forensics?
What is something I could tell my class and teachers that would surprise them about forensics?

Asked by Ella over 5 years ago

"Touch" DNA or "Contact DNA" can obtain a profile from an item that someone merely touched: https://en.wikipedia.org/wiki/Touch_DNA

I would say Rapid DNA, which can provide a profile in less than two hours and used in the battlefield, but that's been around since 2014.

And though you've seen it on TV every day for 50 years, it has not been possible for the average latent print examiner to scan in a fingerprint and search every person who's ever been fingerprinted, including job applicants and military. Most databases would be just county or state wide, and may or may not include job applicants (or staff) depending on the preferences of the agency, and certainly not the military, ICE or Interpol. At my department we only got the ability to remotely search the FBI database last year.

Hope that helps!

How long does saliva DNA stay on an object? In other words, for how long the DNA is detectable?

Asked by Aj over 5 years ago

That depends entirely on the circumstances. If a sample of anything--blood, saliva, semen--is properly dried and kept in relatively dry conditions at a steady low temperature, or even frozen, it can last for decades. If the temperature and humidity vary greatly, then the sample could break down. If it's stored in plastic or airtight when wet it could rot and decompose.

What would you say is the best way to get into forensic science? I’m either thinking of going into a forensic science course or doing a chemistry/ biochemistry Uni degree?

Asked by Katie about 6 years ago

Either is good. It depends a bit on what you want to do. If you want to work crime scene, then general forensic science is probably good. If you want to go into toxicology, then chemistry, and if DNA, then biology or genetics.

Hope that helps.

I knew the Coroner, the people who ran a forensics company, and other people who worked for them. How where they able to eat in the little room next to the morgue? With windows to see and the smell? They would eat lunch in there.

Asked by Ray about 6 years ago

Did it every day. If it bothers you, you probably don't want to work there. Though our lunchroom was on an upper floor so there was no sight, just sometimes smells.

Is blood soaked evidence washed after testing? For example a leather glove. Would it just be dried out and kept like that or do they clean the blood off.

Asked by bailey almost 6 years ago

No, nothing is cleaned. It’s just dried and then kept as is. For one thing you might want to do more testing in the future so you’d never want to wash your evidence away.

What is the most complicated case you’ve ever worked and why?

Asked by Captain Coke almost 6 years ago

I can't think of any one in particular that was the most 'complicated'--many were difficult and complicated for different reasons. Forensics is only part of the whole investigation, so things really get much more complicated for the detectives who not only have to absorb the information we're giving them but deal with victims, witnesses, suspects, documentation, records, warrants and prosecutors. I worked one where the victim had been taken to three different places before the body was dumped and burned, so there were indoor scenes, outdoor scenes, the suspect's house to deal with. Right now we're dealing with one that spans 30 years, so trying to find reports and piece together who did what and when and what, if anything, still remains to be done. And we had one earlier this year that had inexplicable behavior by about 9 different people over three days and all to cover up an accidental death. Hope that helps.
