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.

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 almost 5 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!

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.

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?

Hi, Lisa Black I am Bobbie-Sue besides fingerprints or DNA what are other things that are looked at? Toe prints? There I am sure many other things besides those two things... right?

Asked by Bobbie-Sue about 5 years ago

We can compare footprints just as finger or palm prints, but there isn’t a database of footprints so you would have to have standards of the suspect’s feet. Otherwise I don’t know what you mean by ‘looked at.’ Everything is looked at, in a sense—there’s ballistics, fibers, bloodstain patterns, arson evidence, toolmarks, video and photo analysis, paint, glass, etc. and etc.

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.

someone is alleged to have worn a t-shirt for over twelve hours on an 88 degrees day,dancing,drinking,and playing pool,but DNA testing revealed none of his DNA was found in said shirt.What are the odds of that,if not possible?

Asked by filomenasmith@yahoo.com almost 5 years ago

That sounds odd, but were they looking for blood or semen stains in particular, or just the DNA of whoever wore it?
