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.

How (or where) can I get someone to review an autopsy for mistakes or inconsistencies, if corruption is suspected from the investigative agency that was present, and influential during the examination?

Asked by Lina over 6 years ago

You would need another forensic pathologist to review the work of the first forensic pathologist.

Best of luck.

I am writing a paper for college about orthotolidine tests. Why do you think they were discontinued and have you ever used it in your professional career? Would you consider a positive orthotolidine test as conclusive evidence in court?

Asked by Penny Kap over 6 years ago

I believe it’s a presumptive test, so it would not be considered ‘conclusive’ evidence, only an indication that further test (like DNA) would be appropriate.

I have never used an orthotolidine test, unless that’s the reagent in the Hemastix test strips. We used those a great deal at the coroner’s office—they’re very handy, but can have false positives. Deciding what reagent to use will always be a function of ease of use, possibility of false positives and false negatives, expense and hazards (such as carcinogenic properties).

Best of luck!

If you were given a 20GB hard drive that had been used to image an 8GB USB device and
found during analysis that more than the 8GB image was on the disk, what would this
indicate? How would you then proceed?

Sorry, but I’m not trained in digital forensics. I have absolutely no idea.

I am taking a Forensics class in High school and I am looking to ask some questions of a Fiber Analyst. Do you happen to be a Fiber Analyst or do you know know anyone who I can contact?

Asked by Bailey almost 7 years ago

I used to be the hair and fiber analyst. Unfortunately it's increasing rare to find fiber analysis done at labs. Perhaps I can help you.

How long does a body have to be exposed in warm temps before it starts to deteriorate?

Asked by LookingForJustice about 7 years ago

Bodies begin to deteriorate immediately, but the process might progress more slowly or less slowly depending on temperature, humidity, exposure or any medical conditions of the victim.

Is it dangerous to be a forensic scientist ?
Thanks

No.

Lisa, I'm a published author working on a novel. Woman was murdered and buried 20+ years ago. Can authorities 1) determine her identity and 2) Can they tell whether she was pregnant when she died? Thank you in advance!

Asked by Jack almost 7 years ago

Answer to both is: maybe. If she was buried in the earth over 20 years, unless the ground was always frozen or so dry that she mummified, there will most likely be only skeletal remains left. So they might be able to establish identity from dental records, medical device implants (say a pacemaker or an artificial hip), or something left in the grave with her (like an ID card). I believe anthropologists can tell from the pelvic bone if someone has given birth, but not if pregnant at the time of death. However depending on how far along the baby is, they might have their own bones present so then it would be obvious. Best of luck!
