Forensic Scientist

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.

Hello,

How do you go back and re construct the last 24 hours of someone’s life

Asked by Margarita about 5 years ago

I’m sorry but I have no idea. that would be the detective’s job, not mine.

Best of luck!

What is the cost to a criminal defendant to have a print run through the FBI's AFIS system? Has that cost remained the same from 1999 through the present?

Asked by MsM over 4 years ago

I'm sorry but I have absolutely no idea. I didn't know there was a cost. I would have guessed that their attorney could request a court order to do so from the judge and the police agency that has the print would take care of it, but I really don't know. Sorry I can't be more help.

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

Asked by Richard over 5 years ago

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

Saying that they DID do what ever it is they are being accused of?

Asked by Mike over 4 years ago

There have been a few cases in which I testified where the defendants were found not guilty, and I was fine with that. In some there simply wasn't sufficient evidence, in one it was clearly self-defense, in two the defendants were charged with murder and I figured it should have been manslaughter. But that's why we have a jury system, and they did a good job.

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 almost 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.

Have you ever done a case where you did not think the person who did it deserved to be locked up?

How did you handle it?


If you have not. How would you react to that? If you’re asked to do a case but don’t agree the person should be arrested?

Asked by Mike over 4 years ago

My job isn't like TV--I'm not involved in every single aspect of the investigation. My job is to provide forensic support to the detectives, so in any given case I estimate I know perhaps 20% of the overall information relating to the crime. I don't know what witnesses, victims, suspects have said, what financial or phone records might show, etc. etc. The detectives would probably tell me if I asked, but I'm usually too busy with all the other cases to ask.

Who to arrest and who to prosecute is up to the detectives and the prosecutors. They don't ask my opinion, and in light of the first paragraph, I probably couldn't give them an informed one.

What are the top 10 most fun/ interesting facts about your job?

Asked by Miki23 almost 5 years ago

Wow, that’s a tough question! I’m not sure I could come up with ten.
