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 can we detect the GHB from urine sample by LCMS?
Is there any simple method?

Asked by Eman over 5 years ago

I’m sorry but I’ve never worked in toxicology. Sorry I couldn’t help!

How reliable are drug tests? The ones that turn colors. I seen where a dude had doughnut glaze on the ground and it tested positive (no thats not a joke lol).

Asked by Darren over 5 years ago

I'm sorry but I've never worked in toxicology, so I've never tested drugs with any kind of test.

Sorry I can't help!

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.

Biggest pet peeve out of co workers? I also heard working at police and sherif departments your lunch is always stolen is this true?

Asked by Mike almost 6 years ago

That's never happened to me at the police department, but then there's only my forensic unit with access to our refrigerator so it's not a problem. But it used to happen in the lunch room at the coroner's office all the time! I injected candy with hot sauce once. That stopped it for about a week.

Should we be able to use torture on suspects during interrogations?!

Asked by Dan over 5 years ago

How does that question relate to forensics?

I would like to know if an autopsy conducted on a woman buried in dry soil for three years
could determine if she had an abortion, being the cause of her death.
Thank you
Karen

Asked by karen_west@bigpond.com over 4 years ago

That’s a good question…I know that the human body will either decompose or desiccate, so if the conditions were right and she dried out instead of breaking down, then the body might be largely preserved. But what could be determined from an autopsy would be a question for a pathologist, I’m afraid. Sorry I’m not more help.

When you started work in forensics did your job train you or were you having to rely on what you learned in college?

Asked by jsk789 over 5 years ago

They didn’t have forensics degrees when I went to school, so learned all the forensic tasks were on the job or continuing education courses. But the science background helps with understanding lab procedures, preparing reagents, and of course explaining what’s going on during the various processes.
