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.

Hi,

You recently advised that a simple black powder would reveal glove prints deposited by Nitrile gloves. Would Latent Silk Black Print Powder, manufactured by a company called Sirchie be a good choice?

Thank you.

Asked by Richard Gray about 5 years ago

Sure--any good quality black powder should have the same effect.

How can we detect the GHB from urine sample by LCMS?
Is there any simple method?

Asked by Eman almost 5 years ago

I’m sorry but I’ve never worked in toxicology. Sorry I couldn’t help!

I would like to know if an autopsy conducted on a woman buried in dry soil for three years
could determine if she had an abortion, being the cause of her death.
Thank you
Karen

Asked by karen_west@bigpond.com about 4 years ago

That’s a good question…I know that the human body will either decompose or desiccate, so if the conditions were right and she dried out instead of breaking down, then the body might be largely preserved. But what could be determined from an autopsy would be a question for a pathologist, I’m afraid. Sorry I’m not more help.

Are there any famous cases in history that involved thin layer chromatography (TLC) that you are aware of? Or any interesting facts many would not know?

Asked by Mike over 4 years ago

I”m sorry but I”ve never used thin layer chromatography. If I had, it most likely would have been to distinguish extracted fiber dyes. As far as I know it’s the only way to determine if natural fibers likely had the same source.

I have to choose my major so are there branches of this career like examining bodies etc or does a forensic scientist have to do it all and what subjects should i take in school the subjects that my school provides are phys bio maths chem

Asked by dania over 5 years ago

All of those are good. Take as many science courses as you can. Much depends on where you want to work and what you want to do. If you want to do DNA analysis and testify in court about it, you may need a PhD in genetics. If you want to work at crime scenes bagging and tagging evidence, you may need only a high school diploma, with added hireability for advanced degrees. The only way to know is to check job opening notices or call the agencies and ask. I would also suggest that you look for schools that have hands-on lab work with forensic topics such as fingerprints or crime scene work. Best of luck to you.

I need to know how can I get blood group from old dried blood?

Asked by Mou almost 5 years ago

They used to do that in serology, taking threads soaked in the blood and putting them in tiny pools of blood type reagents. I don’t know exactly what the reagents were, sorry, that had never been part of my duties. But if you research old serological techniques you should find it.

Best of luck!

Biggest pet peeve out of co workers? I also heard working at police and sherif departments your lunch is always stolen is this true?

Asked by Mike about 5 years ago

That's never happened to me at the police department, but then there's only my forensic unit with access to our refrigerator so it's not a problem. But it used to happen in the lunch room at the coroner's office all the time! I injected candy with hot sauce once. That stopped it for about a week.
