Forensic Scientist

LIsa Black

Cape Coral, FL

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.

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 Parbh over 9 years ago

I have no idea, so I asked my co-worker. She said:My first question would be was the 20GB forensic wiped? Was it completely empty when the 8GB was put on it?Second, does the software that you use to image produce working files or executable programs that are needed to view the image? Otherwise 8 GB is 8 GB so there can't be more.

For undergraduate studies, is it recommended to take Forensic Science or should we take a broader natural science such as Chemistry or Biology? This is of course considering the applicant is aiming to become a Forensic Scientist in the future.

Asked by Detective Dick Gumshoe about 9 years ago

I would suggest biology or chemistry, but that was what everyone took when I started out, so I may be behind the times. Your best bet is to call the crime labs you might wish to work at and ask what they prefer. Also check employment postings on the forensic organizations websites, such as IAI and AAFS. That's the only way to be more certain what they actually want.

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 almost 10 years ago

Sure, I will email you.

can you tell the age of pharmaceuticals - specifically Ritalin/methylphenidate - like how many years ago it was made?

Asked by rogernono about 9 years ago

I'm sorry, I wouldn't have any idea. Do you mean dating the actual pills, or once they're in a person's system? If the former I think you'd have to ask a chemist, if the latter, a toxicologist. Sorry I can't help.

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 about 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.)

What type of decisions do you make

Asked by Angel about 9 years ago

How to best process or obtain a piece of evidence.

When looking at a murder scene, could you simpky check the body for fecal matter or urine in their groin area to see if that is where the murder took place?

Asked by Quincy almost 9 years ago

I think you mean to check for that wherever they're lying to see if the body had been moved?

Well, not everyone evacuates upon death. Also the clothing absorbs most of it, and any that leaks through could also have leaked through after being moved. But yes, that could be an indication that the body had been moved just as bloodstains would.

Hope that helps!
