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'm writing a short story and would like to know what a body would decompose like after being left unburied in a forest in January, heavy snowfall, and discovered in February? Thank you so much!

Asked by rose over 8 years ago

I'm not an expert in that particular aspect, but I know from experience that it will make a big difference if the area was continuously frozen as opposed to freezing, then thawing, then freezing again and so on. If it was continuously frozen there might not be too much decomposition at all. If it freezes and thaws continuously then it could be quite decomposed, especially if its not covered with anything like dirt or even leaves. Plus under those circumcstances I would expect a lot more animal activity.

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 over 9 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 over 8 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.

Hi. Will a combination of chlorine bleach, gasoline and paint thinner destroy blood DNA?
Thank you :)

Asked by Ayden about 9 years ago

As far as I know, the chlorine bleach alone will do it.



If a man masturbates a few times on a towel...And his girl friend urinates on it and then wipes her self down there with it. Would it be possible to find semen in or around her vagina?

Asked by Brian over 9 years ago

I really don't know--I suppose it's possible but I don't know how urinating on it would affect it. I also don't know why one would urinate on a towel. And it sounds like you're trying to find an innocent explanation for your girlfriend's parents on the occasion of her unexpected pregnancy. Either way,, good luck.

What are the educational requirements for an entry-level position in this line of work?

Asked by Violet over 9 years ago

The requirements are whatever your employer says they are (same with your job title). DNA analysts are often required to have a PhD in genetics. At the coroner's I had to have a BS in one of the natural sciences. At my police department they only require a high school diploma, but give extra points for advanced schooling so we all have BSs. 

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 about 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.
