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.

Hello! I'm writing a career paper for college about forensic scientists. I was wondering if I could interview you and ask a few questions? My email is iy7997kl@mycentury.onmicrosoft.com Thank you!

See above.

How long can GSR last on clothing or on a person?

Asked by Jailah almost 11 years ago

On the shooter's hands, not very long. When we did GSR testing we would not do it if more than 4 hours had elapsed since the shooting. On clothing, it could depend on the type of material and how far away the item was--if it's a smooth fabric it would probably brush right off, but a more fuzzy type of thick material might get some particles stuck in it.

That was talking about primer residue. Gunpowder residue is bigger, heavier, and hot so it can fuse to some fibers or get 'stuck' to the item by the victim's blood.

Say that there was a crime scene with trama to the head and bleeding from the head and specialist forgot to take the temperature of that body, what is another way to determine the time of death?

Asked by bryce over 10 years ago

Time of death is not determined as precisely as it is on television, I know, and they often use a number of factors to make an estimate such as when the person was seen last, mail piling up at the door, rigor mortis, lividity, etc. But honestly a pathologist could answer that question much more accurately than I could. They are the ones that determine TOD.

Approximately how many cases do you think you have solved in the last year?

Asked by Danielle almost 10 years ago

I don't solve cases. Detectives solve cases. I suppose I actually 'solve' them when I get a fingerprint hit for a burglary where there would have been no other way to ever identify the burglar. That happens maybe 5-10 times a year. Otherwise forensic science is usually confirming or eliminating factors that are already suspected, and often provides information (say, what caliber of gun was used or where the burglar got into the house) that doesn't point to the identity of the criminal but adds details to the overall event.

Hi I wounder how far has sience in forensics reached. Do you today have the ability to se emosional marks in the air? Strong emosions can leave a mark. like a fight that some sensetiv people can feel in a room even after it took place.

Asked by Jenifer over 10 years ago

I have never heard of that.

When examining a fingerprint, do you lift the print first then swab for DNA?

Asked by Renee over 10 years ago

That's always a good question. Black powder or superglue will not ruin the DNA, so we can photograph the print and then swab for DNA. Usually we're swabbing areas that we wouldn't normally be able to get a print from (like textured steering wheels or rough gun grips or the edge of a plastic bottle that someone drank from) so we do one or the other.

If somone ejaculated in a girls or guys mouth they swallow can u find dna can it be found in 5 hoursborbis itbalredy gone
