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 about 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.

Can you test for how long dna evidence is present. Like if I cut myself on accident three days ago could you time stamp that without me telling you how long ago the accident happened.

Asked by PF almost 9 years ago

No. There is no time stamp on DNA, so far as I know.

I am looking at becoming a DNA analyst working with hair, blood and gunshot residue samples, would it be better to get a degree in Forensic Science or a degree in Biology?

Asked by ssosiak1 about 8 years ago

If you're going to be a DNA analyst, you will probably not be working with gunshot residue as well. DNA labs are tending to want their analysts to have a PhD in genetics and focus solely in that area, but it would be best if you called labs at which you might want to work and make sure. Best of luck.

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.

What type of decisions do you make

Asked by Angel over 8 years ago

How to best process or obtain a piece of evidence.

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 almost 9 years ago

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

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 almost 9 years ago

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