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.

A Man is found dead near rail track falling from a train. Can a forensic expert say whether he jumped or accidentally fell or pushed by somebody from train?

Asked by Maria Rose almost 6 years ago

I see that on TV all the time but I have a hard time believing it. But I don't know personally. Sorry!

Do you ever go through computers and what’s the weirdest thing you have found? Do you run through everything? And do you ever find things that most people think would be gone

Asked by Dillon about 6 years ago

I do not, as I'm not trained in digital forensics. But my coworker who is says that many many times, what people think is deleted is not really deleted.

Assume a swimming pool on a yacht was filled with regular tap water and chlorine. A person drowns in the pool. The body is dumped over board and found within hours. Could lung water be tested chemically to help discern the true facts?

Asked by PT O'Neil almost 7 years ago

As far as I know that is possible. Whether a medical examiner’s office would actually test the water in the lungs in a case of apparent drowning is another matter. There is also the possibility of ‘dry-drowning’ in which the throat closes and no water gets in the lungs. A pathologist told me once that drowning is sort of a ‘negative diagnosis’ in that, if no other cause of death presents itself and the person is found in water, then drowning is assumed. Sorry I can’t be more help!

How is it determined that rape occurred after death?

Asked by JODI over 6 years ago

That’s an excellent question that I”m sorry I can’t answer. You will need to ask a pathologist. Sorry I couldn’t be more help!

Hi Miss, I'm a student from Australia conducting a Research Project and my question is 'how have forensic methods evolved through the last 40 years to improve the rates of crimes solved'. As a professional, would you be able to elaborate on this?

Asked by Kate Flynn over 6 years ago

Wow, that's an extremely broad question. I don't know if the rates of crimes solved have been increased greatly--perhaps in some crimes like rape or murder but perhaps not in other crimes like burglary and theft. But certainly the biggest advances in forensics have been DNA and the connectedness of fingerprint databases. Less specific but perfectly valid analyses like pollen, soil, and other trace evidence examination have gone by the wayside. And digital analyses such as the downloading of cell phones and personal computers are helping solve crimes more and more, but then people didn't have cell phones or personal computers 40 years ago so I'm not sure that counts!

I hope that helps!

I know they use interrogation techniques, polygraphs, and have experts who recognize truth and deception. But do and could someone use hypnosis?

Asked by DJ almost 6 years ago

Supposedly, but I don’t know of any cases personally.

Can a hair test that came back false positive for alcohol be retested by another lab?

Asked by Joe almost 6 years ago

I don’t see why not. But I wasn’t aware hair could be tested for alcohol, I thought it was only drugs and heavy metals.
