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.

Can a 9mm use 38 bullets

Asked by Dianna over 9 years ago

No. A .357 can shoot .38 bullets (not vice versa, or the gun will blow up) but 9mm can't shoot 38 bullets because they're shaped a little differently. It's confusing because what we call .38 caliber are actually .357, and 9mm is actually .380--in size, but a 9mm gun cannot shoot .380 bullets. You would have to read the forensic report carefully and maybe ask for clarification. I've never worked in ballistics, so perhaps there's a chance that the report is saying that the projectile had a .380 diameter, not that it was a .380 bullet, in which case it could have come from a 9mm gun?

I have never heard of that.

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

Asked by Jailah over 10 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.

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.

My brother-in law, 24y.o. healthy male is with friends chat/laughing and laughs extra long, stops, head hangs down. Within minutes he passes away. At the time, drinking an energy drink and ate a peanut bar before. Post mortem, just scorched stomach??

Asked by Curious about 10 years ago

I'm sorry, I wouldn't have any idea. You'd have to ask a pathologist.

Girl claims rape, boy says didn't happen. DNA came back inconclusive from rape kit except something in girls underwear they say is boys. How is that possible when nothing was discovered on girls body of boys, anywhere?

Asked by Momma over 9 years ago

Because human bodies are in constant flux. Cells slough off, fluids wash out other fluids, but a stain on a piece of cloth doesn't change.
