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.

What's the most important thing forensic science can do today that it couldn't do 5 years ago?

Asked by ChrisnMike over 9 years ago

I would say 'touch DNA', which means get a DNA sample from the sweat, oils, and amino acids left by simply touching something. We now routinely collect swabs from steering wheels, gun triggers and tool handles. That doesn't mean they always have sufficient DNA to do anything with, but surprisingly often they do.

What type of classes did you need to take to become a Forensic scientist?

Asked by Nikkie over 9 years ago

If you see the two Q&As above, you can't go wrong with science classes. When I was in college they didn't have courses specifically in forensic science, so that wasn't an option. And different agencies will have different requirements, so you might want to go online and check out the different vacancies to get some idea of what requirements are out there.

For trace comparison, how much glass from a crime scene would you recover in order for a controlled comparison to that found on a suspects?
6 or 12 and where from?

Thank You.

Asked by Mike about 9 years ago

I  don't know what you mean by 6 or 12, but I asked a former co-worker who used to analyze glass in an ICP (inductively coupled plasma) and he said the current state of the art for glass analysis is LA-ICP-MS (LA = laser ablation). This uses a laser to vaporize a small amount of sample and then runs it through both an ICP and a mass spec. (only about $300,000). I'm sure a small amount is a very small chip or sliver. I know when I did glass analysis on an old hot stage we only needed a tiny chip. He also said you should contact Florida International University because it is "the epicenter of glass analysis".

I'm in high school right now and I want to become a forensic scientist. Is there a list of courses I should be taking? Or can you recommend any courses?

Asked by Wendy N. over 9 years ago

You can't go wrong with as much biology and chemistry as you can get, plus some physics and math.

What made you want to become a Forensic scientist?

Asked by Nikkie over 9 years ago

I loved mysteries but didn't want to be a cop. I don't really want to deal with people under stress on a daily basis. This job has enough variety to be interesting but enough routine to keep the homebody in me comfortable.

what college did you go to?

Asked by Nikkie over 9 years ago

I have a bachelor's in biology from Cleveland State University in Cleveland, Ohio.

Hi, I'm writing a research paper. How often do you have to present evidence in front of a jury as an expert witness and has it become more difficult as the popularity of crime dramas has increased?

Asked by Madison about 9 years ago

That depends on a lot of factors. In Cleveland I went to court a lot more often because--since it was a coroner's office--practically every case was a homicide and many went to trial. In Florida at the police department we have few homicides and a lot of burglaries and such, the types of crimes that tend to get pled out or dismissed. So I might go to court twice in one week and then not again for three months. And yes, the popularity of crime dramas has definitely made things more difficult because a jury expects to be 'wowed' with cool science in each and every case, and sometimes that just isn't there. It's not a bad thing that there's increased scrutiny on forensic testimony, of course, only that expectations can be unrealistic--in both directions. It can harm the prosecution's case if the jury expects DNA evidence in, say, a robbery case where someone walked in and walked out and didn't leave any DNA, and it can harm a defense's case if the jury has such faith in science that that evidence is all they give weight to. (Excuse the clunky grammar please.)
