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.

Thanks so much for answering that! Yeh, the criminals used other peoples hair. Would it be possible to blend the different types of hair with water so you could spray it on the scene of a crime? would it be the same result as leaving the hair intact?

Asked by Lisa fan over 9 years ago

Wouldn't that get the whole crime scene wet? And wouldn't a layer of hair indicate that the hair was a diversion, since obviously no one would normally shed that much hair while committing a crime. It scattering hair wouldn't affect fingerprints or touch DNA, which crime scene techs would be looking for more than hair anyway. Most labs don't even analyze hair any more. Also, I should clarify, hair cells don't have nuclear DNA. DNA in hair usually comes from the skin cells that hold the hair in your scalp and cling to the root. So if you're using cut hair there would not be any nuclear DNA to obtain. Mitochondrial DNA is a different type of DNA present in your cells' mitochondria. It will be the same throughout your body but is passed down unchanged from mother to child so it will be identical with your mother, your mother's siblings (assuming the same grandmother), your siblings from the same mother, your first cousins from your maternal aunts, etc. But very very few labs test mitochondrial DNA so it's unlikely it would be tested from your crime scene unless it was extremely high-profile and they had no other evidence to use. And then they'd have to have a suspect to compare it to or it would be useless. (CODIS, the national DNA database, is nuclear DNA.)

I doubt I can help you but I'll try to get the pic.

Many cold cases have unidentified victims but how come they are unidentified when you have fingerprints and hair, etc, i don't understand why cant they know who they are when they have that.

Asked by lily almost 9 years ago

Because not everyone's fingerprints are in a database. You only have fingerprints taken when you are arrested or apply for a job or some other license for which it is required. Not all of those necessarily end up in a database accessible to the agency that has the unidentified person. And DNA such as hair only helps when you have a profile to compare it to--if the unidentified person is a convicted felon so their DNA might have been entered when they went to prison, or if there are family members available to give a sample (in which case you would have to already have an idea of who the person might be). It's not really like TV. We don't have databases of every single person and every single substance known to man.

What is the difference between a forensic scientist and a forensic science technician? Also, would I be able to major in Human Biology to become a Forensic Scientist?

Asked by RTasha over 9 years ago

A forensic scientist, forensic specialist, forensic technician can all be the same job or different jobs--your title is whatever your agency/boss says it is. There's no strict uniform code for titles. Usually any natural science is a good background for forensics. It may depend on whether you intend to work in a lab or on crime scenes. The best way is to look at job postings that interest you and see what the requirements are. You can view job postings on professional organizations' websites such as www.aafs.org or www.theiai.org. Good luck.

How long would it take for a deceased body to drop below 32 degrees centigrade if they were in good health previously and the ambient temp was 17 degrees centigrade. Would the body be cold and blue to touch inside 2 hours?

Asked by Iain over 9 years ago

I'm sorry but I have no idea. That's a question for a pathologist. Sorry I couldn't help!

Hello, I am In high school & I'm doing a project where I have to ask about 8 questions to a forensic scientist, if you are willing to answer them that would be great & if you can email me @breannejanaeruiz@gmail.com that would be even better, thanks!

Asked by Breanne Ruiz about 10 years ago

Sure, I will email you.

Would you be able to tell the difference between hair that was taken from a victim's brush (and planted at a crime scene) and hair that just naturally malted? For example, would hair from a hairbrush have more of a root than a malted hair??

Asked by Caroline about 9 years ago

I don't know what malted means, but I suspect the answer is no. Just brushing hair can pull it out just as in a struggle.
