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 have a friend that wants to be a Forensic Scientist! He recently graduated high school and is transitioning to college. Is there any summer jobs/ internships you would recommend for him that can increase his exposure to the field?

Asked by Carter about 5 years ago

I don’t believe there would be any summer jobs at a police department or crime lab, and internships are usually given to students who are college juniors or seniors. Though they should check with the police department, there might be volunteer or Explorer programs. Otherwise any job that involves lab work might help—not just hospitals but food or water testing sites.

Best of luck to them!

In a situation where fingerprints are planted on the weapon, and the person who committed the assault/murder is holding the weapon with gloves. How do the prints not become smudged or rubbed off?

Asked by Emily about 4 years ago

I would think they’d have to get rubbed off. I don’t know how one could hold a knife tightly enough to stab someone without smudging all the prints on the grip. Guns, despite what you see on television, are terrible surfaces for prints, though I guess if you were very careful and maybe propped the butt on something, I suppose you could use it without grasping and smudging some areas, like the grip (if it were smooth, otherwise it likely wouldn’t retain any prints anyway) or a shiny, chromed barrel. A knife, maybe if it was big enough that you could grip only part of the handle and leave the prints on the other part undisturbed. Or maybe part of the blade if you didn’t stick it in the body all the way. But I would think it would be tough to do.

Hope that helps!

Since, you are in the forensics field. Do you know anything about forensic toxicologists? If so can you elaborate on what you know about this field?

Asked by GunKillerOdin over 4 years ago

Unfortunately, no, I cannot. I've never worked in toxicology. Sorry I couldn't help.

Is there anyone special you worked with?

Asked by Jason over 4 years ago

Could you clarify that question? I'm not sure what mean.

Do witnesses often test positive for GSR residue on their hands? How close would they need to be when the firearm is discharged?

Asked by Cat twigg over 4 years ago

I couldn't tell you--I haven't personally done any studies of bystanders at a shooting. GSR analysis is usually testing for primer residue, which can escape from the gun when fired. So someone could have GSR on their hands if they handled a gun, if they touched a surface near to where a gun was fired, if they handled the gun after it was fired, etc. This is why, though they've stated this on television every day for fifty years, having gunshot residue on your hands doesn't prove you fired a gun. Not having gunshot residue on your hands doesn't prove you have not fired a gun. The particles are very tiny and easily dislodged. These are some of the reasons why most agencies don't do gunshot residue analysis any more. Hope that helps!

What are some advancements from a forensic scientist?

Asked by GunKillerOdin over 4 years ago

I’m not sure what you mean. Do you mean how does a forensic scientist advance in their career, or what scientific advancements have been made by forensic scientists?

Hello what do different colors flags mean? You know those little flags that stick in the ground? What does pink, yellow, green, multicolored, white, etc mean?

Asked by Barney about 5 years ago

I have no idea--are you referring to utility companies marking gas lines, etc? My agency has some flags but we haven't used them recently. I suspect if an agency uses different colored flags it might be some internal coding that they use. Sorry I can't be more help.
