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.

When examining a fingerprint, do you lift the print first then swab for DNA?

Asked by Renee over 11 years ago

That's always a good question. Black powder or superglue will not ruin the DNA, so we can photograph the print and then swab for DNA. Usually we're swabbing areas that we wouldn't normally be able to get a print from (like textured steering wheels or rough gun grips or the edge of a plastic bottle that someone drank from) so we do one or the other.

Hey, I'm very interested in becoming a forensic scientist myself. May I ask, what kind education is necessary to become a forensic scientist. Also where did you apply for your job? Did you go through private training after you were hired?

Asked by Zachary Assante over 10 years ago

If you look through previous answers you'll find a number pertaining to this. Each agency and position may have different requirements so the only way to know is to call the places you are interested in working at and ask them. For my current job I only need a high school diploma but we all have at least a Bachelor's degree. If you want to do DNA analysis they may require a PhD. I applied to the police department that posted the vacancy. Most have online postings now so it's pretty easy. Yes, I've had a lot of continuing education through other police departments and forensic organizations.

Can a forensic Scientist help me solve this quetsion? There was only one murderer.

Asked by Sujee Pundaisen almost 11 years ago

I'm afraid I'll need some more details than that.

what technologies do they use for fingerprinting identification

Asked by nikki over 11 years ago

There are numerous techniques for obtaining fingerprints from surfaces--black powders, colored powders, alternate light, superglue, dye staining. Once you can visualize the print, comparing one to another is done by noting all the information (where ridges end, divide, form a dot, have a scar, etc.) in one pattern and comparing it to another print's pattern. This can be done by a computer so that thousands to millions of prints can be searched quickly, all day, every day, all over the world, but is always confirmed by human beings. Despite what you see on TV!

What requirements do you need to become a forensic scientist?

Asked by stephanie over 10 years ago

It depends entirely on where you work. The requirements are whatever your employer says they are (same with your job title). DNA analysts are often required to have a PhD in genetics. At the coroner's I had to have a BS in one of the natural sciences. At my police department they only require a high school diploma, but give extra points for advanced schooling so we all have BSs. The best way to get an idea is to go to different agencies' websites and look at help wanted postings.

Is it possible to find any semen or blood samples in an abusing crime scene after a while ? Certainly the scene is being cleaned by the janitors but even so with luminol or Christmas Tree Stain can any results of the criminal identity still be found ?

Asked by Mekos over 10 years ago

Who knows? It all depends on where the samples were and how thoroughly the surface was cleaned. If blood was on a glass window and it was thoroughly cleaned, then all of it is probably gone for good. If it's a porous bare wood, then probably not...unless it was thoroughly soaked with a bleach solution. If it's a large area, even if it's cleaned there might still be some left in the nooks and crannies--like in a tile floor, the ceramic may be clean but the more porous grout between the tiles might hold a substance. So there is no way to say it's always possible or it's always not possible. PS Luminol helps you find blood. Christmas Tree stain is used to stain a dried semen sample on a glass slide. It doesn't help you find the semen in the first place.

What is the first thing you look for at a crime scene?

Asked by Lilly123 almost 11 years ago

It depends on the crime, but in general I guess you look for how the perpetrator got in, how they got out, and what they disturbed while they were there. Then I look for what we could get information from (such as surfaces that they had to touch that are smooth and glossy and might have prints, whether they left blood or bodily fluids behind that could be tested, whether they wrote something or used something that could point to their identity, etc.).
