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.

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.

What is the point in giving a poly graph if it’s not even admissible in court except for in specific circumstances? (Usually if only the defense and prosecutors agree)

Asked by Zarah about 6 years ago

That's not something I have anything to do with--it's the detectives' and/or attorneys' decision. I supposed they think if they get results that are really surprising it can hint if they're looking at the right people or not.

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!

Hi,
What is the difference between forensic observation & forensic inference?

Asked by Caitlyn almost 6 years ago

I'm not familiar with those terms. Sorry I can't help!

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.

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.

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.
