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.

Are you pretty much a unsworn detective? Do you do pretty much everything a detective does with the exception of arresting people or charging people?

Asked by Rae over 4 years ago

No. I do lots of stuff detectives don’t do, like lab analysis, scene reconstruction, latent print comparison, etc. And they do tons of stuff I don’t do, like track down victims/witnesses/suspects and interview them, run criminal histories, request search warrants, and so on. So our jobs are really very different. We are there to provide the forensic support for the case, but forensic topics are only part of any case. Hope that helps!

See next answer.

Also, is it possible to specifically detect that the DNA is from saliva and nothing else?

Asked by AJ about 5 years ago

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

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 over 5 years ago

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

What is something other scientists do as well as officers such as patrol and detectives that annoy you or even piss you plumb off

Asked by Johnathan almost 5 years ago

Usually I'm annoyed most often by people asking for things to be done immediately while ignoring a) that we are working on more cases than just theirs, b) that some processes take time, and/or c) that what their asking for isn't going to prove anything for them anyway.

As for fellow scientists, the worst offenses are a) finding typos in my reports and b) taking the last piece of cheesecake out of the communal fridge.

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.
