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.

Hi,
I'm worried I wouldn't be able to handle seeing the bodies knowing what they went through. Like I read about children that are abducted murdered and dumped and it scares me. Have you investigated a child murder? How do you distance yourself?

Asked by Landon over 9 years ago

I've been involved with a number of child murders but in every case the child was killed by someone in their own family, usually a parent. In one case a 6 year old was shot by an acquaintance of his older brother's, but the 6 year old wasn't the target, simply an inconvenient witness. I've never worked one where the child was abducted. I don't have chilidren so it's actually easier for me than for people who do. To me it's largely the same as any other murder, though harder in some ways because the victim looks so vulnerable. You handle it because there's so much to be done and you have to do it right, so thinking about all that keeps you from thinking about the tragedy of this young life.

Many cold cases have unidentified victims but how come they are unidentified when you have fingerprints and hair, etc, i don't understand why cant they know who they are when they have that.

Asked by lily over 8 years ago

Because not everyone's fingerprints are in a database. You only have fingerprints taken when you are arrested or apply for a job or some other license for which it is required. Not all of those necessarily end up in a database accessible to the agency that has the unidentified person. And DNA such as hair only helps when you have a profile to compare it to--if the unidentified person is a convicted felon so their DNA might have been entered when they went to prison, or if there are family members available to give a sample (in which case you would have to already have an idea of who the person might be). It's not really like TV. We don't have databases of every single person and every single substance known to man.

Will a dry blood stain on rocks, say the interior of a cave, appear red after at least a year or would the stain be darker or change because of the conditions within the cave?

Asked by MK over 9 years ago

It will turn a dark red brown once it's completely dry, and will stay that color so far as I know if conditions stay consistent. If it changes further it would probably just fade a bit.

Do firearms have a unique spray pattern when fired? Something similar to a fingerprint?

Asked by Marco over 8 years ago

No. You might be able to estimate muzzle to target distance from a spray pattern, but not firearm type or brand.

Would there be DNA left if someone used a forge and turned a murder weapon (say a knife) into something else, or maybe just folded the steel multiple times?

Asked by RDSBandit about 9 years ago

I'm fairly sure that the high temperatures used in melting metal would destroy any DNA.

How long would it take for a deceased body to drop below 32 degrees centigrade if they were in good health previously and the ambient temp was 17 degrees centigrade. Would the body be cold and blue to touch inside 2 hours?

Asked by Iain about 9 years ago

I'm sorry but I have no idea. That's a question for a pathologist. Sorry I couldn't help!

Hello, my name is Maria and I'm currently a High School senior. For my college and career project I need to interview someone in my field of interest which is forensics. Is it possible I could interview you through FaceTime or something? Thank you:)
