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.

Hi! I was wondering something about timing. Say a kidnapping takes place in a hotel room. How long is the room cordoned off? At what point is the evidence collected and taken away? When can the room be let again? (Working on a novel!)

Asked by Nico over 5 years ago

We’ll hold the scene as long as we need to get everything done, and that could be a day or two or three, but for a kidnapping it probably wouldn’t be more than a day, just enough to collect all the victim’s stuff, and collect fingerprints, hairs, fibers, anything that might belong to the kidnapper. We eventually get tired and want to go home (though we can go and come back, so long as it hasn’t been ‘released’) and the police department don’t really want to hold it longer then absolutely necessary, because they have a cop or two sitting there doing nothing but guarding the scene, and it takes them off the road. Hope that helps!

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 about 6 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!

What training did you need and experience? Police academy, collage, trade school, etc? Did you get straight into this position or did you have to work up from somewhere?

Asked by David over 5 years ago

Again, titles and job requirements aren't uniform, so the only way to know is to call the crime labs in your area or whereever you might be interested in working and ask them. At the coroner's office we had to have at least a bachelor's in a natural science (this was before they had forensic science majors). At the police department where I am now, they only require a high school diploma but you get more points in the interviewing process for having a four year degree, so we all have one. You can also go on the websites for professional organizations such as the American Academy of Forensic Sciences and check out their job vacancy postings and see what the various positions require. Good luck.

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 almost 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!

How is it determined that rape occurred after death?

Asked by JODI about 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 do you know about Forengsic’s regarding suicides?

Asked by Linda over 5 years ago

That’s a very broad question. What specifically do you need to know?

What is the correct procedure to gather DNA doing a mouth swab and if it's not done correctly is it considered contaminated

Asked by Britni over 5 years ago

I'm sorry, I was sure I answered this long ago! Collecting buccal swabs is very easy--they come in a kit with everything necessary plus instructions for rubbing the swabs on the inside of the mouth and then packaging. Anyone could do it. I've never heard of a case where it was considered contaminated.
