Cape Coral, FL

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.

If I am wearing thin, latex gloves, is it possible for me to deposit my fingerprint through the glove and onto the surface I am touching?

Thanks.

Asked by Richard Gray about 6 years ago

Apparently experimentation has shown it is possible. It gets more likely the longer the gloves are worn.

Why don’t they let civilians interview suspects?

Asked by Jessica about 6 years ago

Because that's not our job. That's the detective's job. They're in charge of and responsible for the investigation.

Also, what is your opinion on auditors?

Asked by Cale almost 6 years ago

I don’t know what you’re referring to.

Does it help my chances of employment if I am a certified peace officer? I know your a civilian but if having the added peace officer certification along with everything else does it help, hurt, or make no difference? Plus I get to carry a gun and badge

Asked by Parker about 6 years ago

I would think it would help because it would show some familiarity with law enforcement agency procedures. Even if you work for a completely civilian agency such as a medical examiner’s office, you would still be interacting with law enforcement constantly, so I would think it would help. Though even if you can carry a gun and badge in your everyday life, you probably wouldn’t be able to carry it on the job unless it was all right with your employer.

What's the best way to highlight and uncover gloveprints left by Nitrile gloves from a surface?

Asked by Richard about 6 years ago

Usually simple black powder will show gloveprints as well as fingerprints. The bubbly sort of pattern they make will be visible.

I had crash some OLA 2.5 pills with olanzapine 10 mg tablets together and had kept it. Just few weeks back some police officers came to my house n found it. They tested it with forensic and it came back as heroin.
Please can you explain why

Asked by Malvin about 6 years ago

I’m sorry but I can’t. That’s a question for a toxicologist. I don’t know anything about drug chemistry.

If a attacker OC sprayed someone and robbed them is there chemical tests to see if the spray that was on the victims face and the Pepper spray on the suspect to see who did it

Asked by Question over 5 years ago

That’s a good question that I’m afraid I can’t answer. I’m sure there is some way to determine the chemicals used in pepper spray. But this would be affected by a) how long does it remain on the skin before the skin absorbs it and b) most forensic chemistry labs are set up to detect illegal drugs in urine, blood or gastric contents. Identifying any kind of poison or other substance may require equipment or reference databases they don’t have.

Proving it’s the same batch of pepper spray may or may not be possible. I”m not personally involved in this kind of testing, but I can assure you it is not like television. We had a series of cases and wanted to determine the exact composition of drugs with percentages of fentanyl, heroin etc. Turned out while nearly every crime lab can determine if a drug is present, there were only one or two labs in the entire country we could find that could determine percentages, and they charged an arm and a leg. 

Sorry I can’t be more help.
