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.

Do you do one on one or group tutoring? For forensic Science?

Asked by Sam over 7 years ago

I’m sorry, no. I don’t feel qualified to do that.

If someone takes their own life by hanging will they have rope fibers on their hands (cotten rope), will the furrow be completely around their neck and if the person is right handed will the knot be on the right side? Thank you

Asked by Kim over 7 years ago

They would most likely have rope fibers on their hands whether they hung themselves or were strangled. No, the furrow will usually get less deep and maybe disappear, depending on how tight the rope is, toward the spot where the knot is since it is usually higher up on the body as gravity pulls the body downward. As far as I know the location of the knot will depend on where it’s tied, if it’s slid around before suspension occurs, and the structure of the knot (if it slips or not). Being right or left handed shouldn’t make a difference therefore.

Can you be multiple different types of a forensic scientist?

Asked by Molly about 8 years ago

Most people are cross-trained in more than one area. In smaller agencies people might have to wear a lot of hats.

Mrs. Black, I'm a freshmen in college and would like to know if you'd allow me to conduct an interview with yourself over email? This is for one of my classes since I am highly interested in becoming a csi.

My son died recently and his keys were in his pocket. They gave me back the keys and wallet in a baggie and I need to clean them. I don't want to open the bag without knowing the best way to do it without the smell and such being overwhelming?

Asked by lmc almost 8 years ago

I’m so sorry for your loss. My advice would be to use rubber gloves and take the items to a porch or some dry outside spot if it’s not going to rain for a while, or the garage or utility room if so. If you’re sensitive to smells you might use swimmers nose plugs or a bandana tied over your face. Spread the items out on a clean paper bag or newspaper (or wax paper if there’s some pieces of paper in his wallet you want to keep. Anything that can be wet, like car keys or plastic cards, dip or wash them in a container of water with some bleach in it, then let dry. Let all the stuff in the wallet dry if necessary, then keep what you want and discard the rest. Some of the smell will dissipate the longer its left to dry but if it’s something that can’t be soaked in bleach, you may never get a smell completely out, as far as I know. Best of luck.

Is it dangerous to be a forensic scientist ?
Thanks

Asked by Tatiana about 8 years ago

No.

Thank you so much for getting back to me! What kind of science did you use as a Fiber Analyst? Did you use biology, chemistry, etc.? What’s your typical day like as a Fiber Analyst? Is most of the work done at the crime scene or in the lab?

Asked by Bailey over 7 years ago

Biology would help with the natural fibers (like cotton or fibers from plants, or hairs from animals like wool) and chemistry helped with analyzing synthetic fibers with polarized light or fourier transform infrared spectroscopy. Those last two don't work on natural fibers because they're not consistent all the way through like a synthetic fiber, that comes out of a machine.

Fiber analysis was usually only examined in cases of stabbing, strangling or bludgeoning, where there had to be close physical contact between victim and suspect. (A gunshot didn't mean there had to be contact.) It was only a small part of my days. Very little is done any more because you can only say the fibers are consistent with having come from a particular sample, you can't say they did, as in DNA or fingerprints. You can't even give a statistic for how likely it would be to find a particular fiber unless it came from the suspect, etc., because we can't know how many items with that fiber are in the environment.

Only collection would be done in the field, to do anything more you would need the microscopes and the equipment at the lab.

Hope that helps!
