Forensic Scientist

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.

I was wondering if the dna from different sources are the same, for example is the dna the exact same in sweat, hair, saliva etc? I ask because I once saw a movie where the criminals threw hair over a crime scene, ruining all the DNA?

Asked by Lisa Fan almost 9 years ago

Your nuclear DNA is the same in the skin cells holding your hair in place, your saliva, your blood, your skin, your bone marrow etc. Your friend's DNA is of course different from yours, but the same in their saliva, their blood etc. The criminals probably threw someone else's hair around the crime scene so it wouldn't match them.

What kind of degree do I need to work in forensic science? What are the pros of being a forensic scientist? What are the cons of being a forensic scientist? How is the job market in forensic science?
This is for an interview assignment.

whats the most challenging thing about your job?

Asked by kenia over 8 years ago

Worrying that I might have missed a piece of evidence at a crime scene or in a lab process.

Can a forensic examiner analyzing evidence distinguish between a latent fingerprint from a bare hand and those produced by someone wearing gloves?

Asked by kayla lions almost 8 years ago

Sure, because fingerprints will have ridges and gloves will not.

As a forensic scientist, what problem have you found that lead to unreliability of forensic science? Any possible solutions?

Asked by yubing almost 9 years ago

"Unreliability of a science" is pretty a broad swipe, so I don't have any idea what you're referring to. Any line of work--government, plumbing, brain surgery--can be unreliable if the people doing the work are undertrained,overeager, arrogant or lazy.

Hypothetical question: if someone died in a brand spankin' new car (very few germs/bacteria, tight seal on the doors and windows) how long would it take for the body to decompose? What would it look like in, say, 75 years?

Asked by Jordy over 8 years ago

Interesting question, but I doubt I can be of much help. A body can do one of two things after death--decompose or desiccate. So it might turn into sludge or it might become a mummy. It might depend on temperature or pH levels (more relevant if the car was buried) to determine which way it would go. Being sealed would definitely slow the process to a crawl. I had a body in an attic once that was partially wrapped in plastic, and after three years the wrapped areas still had plenty of flesh and the unwrapped parts were down to bone.

Do you have any advice on how to prepare for this job

Asked by Angel almost 9 years ago

Take all the science courses you can, and visit and talk to forensic science personnel. You'll find them very approachable.
