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.

Hi I have a job interview tomorrow. Can you tell me the difference about criminal justice DNA and crime Scene DNA? And also what would you do if two samples where switched or contaminated in the lab? And what types of questions came up in interview?

Asked by Jen over 9 years ago

I don't know what you mean by that--DNA is DNA. Samples being switched is one situation, and contaminated is another. Obviously the situation would have to be remedied and the samples re-analyzed. Questions will probably be a combination of general interview questions such as 'what are your strengths' and questions about your specific training and experience in forensic topics. Good luck!



Very very sorry to disturb so many times our case pathologist did not examine hyoid bone. He sent it to forensic lab. However flab did not report receiving it. In the concl pathologist declared hyoid bone intact. When he examined hyoid bone?confused

Asked by Raja almost 10 years ago

Okay, so if I'm following this:The pathologist says he sent the hyoid to the forensic lab.The forensic lab says it didn't receive it. The pathologist report says the hyoid was intact.

It seems to me that the 2nd and 3rd statements contradict the first, and since as far as I know pathologists and not labs examine hyoid bones, my guess is that the first statement is an error, either a typo or a misstatement and the bone was never sent to the lab. The only way to know for sure is to ask the pathologist. Just call the ME or coroner's office and ask for an appointment to come in or to phone in order to ask that pathologist a few questions about the report. Such offices are usually very careful to make a family comfortable so I'm sure they will be willing to address your concerns. Best of luck!

Is there a kind of gloves that doesn't leave gloveprints? Asking for a sort of detective story.

Asked by R-Mod almost 9 years ago

Sorry I didn't answer this before, I'm on the road. I've seen glove prints occasionally--a remarkable number of burglars don't bother to use them. But I've never compared the prints to a particular glove because by definition gloves are mass produced and therefore not unique like fingerprints. I've seen ones from cloth gloves, which will leave the knit pattern behind, or latex gloves which will sort of look like a group of random bubbles crammed together.

In the case of a partial hanging (person on knees), if complete rigor has set in when the body was taken down, is it still possible for the blood to pool on the back?

Asked by Terry over 9 years ago

According to a little chart I have tacked up above my desk, livor mortis sets at about the same time as complete rigor mortis, so it could be possible. But you really need a pathologist to answer that.

Do clothes play a key role in terms of clues? If so… how?

Asked by bart white almost 9 years ago

Again that depends entirely upon the circumstances. If someone is shot from a distance, then the clothes aren't going to tell you anything. If someone gets close enough to leave their own blood or their hair on the clothing, then they might.

What is you opinion on the product rule used in DNA match probabilities and is this a reliable statistical method to employ when new DNA profiling multiplexes analyse STR markers within the same chromosome?

Asked by andres11 over 9 years ago

Sorry, but as I'm not a DNA analyst, I wouldn't have any idea.
