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.

Do you have any suggestions for a research topic in forensic science for a class project?

Asked by HG271 about 4 years ago

Wow, that’s a tough question—I can think of projects and experiments, but research....and what ages? I can ask my coworkers for suggestions.

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 about 4 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.

At a postmortem crime scene where hair has fallen out from the victim, over time, is all the loose hair collected for evidence or just some of it

Asked by Leesa about 4 years ago

That would depend a great deal on the circumstances. Any hair actually on the victim that does not appear to belong to the victim would likely be collected. If there was obviously a struggle, if the victim was beaten or strangled, hairs on their hands or caught in their fingers would warrant special attention or any clumps of hair nearby. If the victim's lying on a carpet that apparently hasn't been vacuumed for the past decade, then single hairs might be disregarded. If the person is outside and shot from a distance, then hairs would likely be disregarded.

I hope that helps!

Have you ever done a autopsy on a animaln

Asked by Ryan over 4 years ago

I haven’t ever done an autopsy at all, since I’m not a pathologist. They can be done on animals, usually it’s called a necropsy and may be done by a veterinarian.

Browse through some of the other forums too and you will see the same trends and writing styles. Crazy stories, posting links, asking dumb questions, asking the same question over and over just in a different way, trying to get people mad, spamming, and fhe list goes on the bus drivers seems to he the worst and the wearher guy before he went away was getting spammed every day

Asked by Jessica over 4 years ago

Some people don't have enough to do!

Why don’t they let civilians interview suspects?

Asked by Jessica almost 5 years ago

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

How reliable are drug tests? The ones that turn colors. I seen where a dude had doughnut glaze on the ground and it tested positive (no thats not a joke lol).

Asked by Darren about 4 years ago

I'm sorry but I've never worked in toxicology, so I've never tested drugs with any kind of test.

Sorry I can't help!
