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 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 almost 7 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!

I made a cast of a boot I found in dirt. When it is dry and I collect it as evidence, what kind of bag do I put it into? A large paper bag, a plastic Ziploc bag, or another type of container?

Asked by Sam about 7 years ago

Large paper bag. Casting agents usually warm up so that might create moisture inside a plastic container or bag. A cardboard box might be good as well to give it enough support to keep it from cracking.

Can you extract DNA from human poop?

Asked by Jessica about 7 years ago

Yes. I don’t know if it’s actually from the poop or from the skin cells sloughed off on it, but you can.

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 almost 7 years ago

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

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?

Asked by MK about 7 years ago

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