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.

Have, is, or are there any of your books that are, is, or will be a movie?

Asked by 272 almost 6 years ago

Trace Evidence, my first book, was optioned and I wrote the screenplay for it. But the producers couldn’t sell it and had to give up. I’ve had nibbles on other books but nothing yet. I keep hoping!

How would you determine if the dye on two pieces of thread are the same? Would you use Ramen Spectroscopy?

Asked by Mike over 5 years ago

That's an excellent question that unfortunately I can't answer. One probably would use it, but back when I did hairs and fibers it was generally thought that the only way was to extract the dye and do thin-layer chromatography, which we didn't have. We also didn't have a Ramen, so all I could do was microscopic comparison.

Best of luck!

At a postmortem crime scene where hair has fallen out from the victim, over time, is all the loose hair collected for evidence or just some of it

Asked by Leesa about 5 years ago

That would depend a great deal on the circumstances. Any hair actually on the victim that does not appear to belong to the victim would likely be collected. If there was obviously a struggle, if the victim was beaten or strangled, hairs on their hands or caught in their fingers would warrant special attention or any clumps of hair nearby. If the victim's lying on a carpet that apparently hasn't been vacuumed for the past decade, then single hairs might be disregarded. If the person is outside and shot from a distance, then hairs would likely be disregarded.

I hope that helps!

Was this election stolen from Trump?

Asked by asdfasdf over 5 years ago

What does that have to do with forensics?

Also, is it possible to specifically detect that the DNA is from saliva and nothing else?

Asked by AJ over 5 years ago

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

What work do you do on a daily basis?

Asked by Janessa Dillon over 4 years ago

At my department I mostly work with fingerprints, analyzing and comparing fingerprints that I collect off pieces of evidence or pick up at crime scenes or ones that the officers submit after they collect them at crime scenes. I will also go to crime scenes, photograph, collect prints, items of evidence, maybe test for blood or collect samples of blood with sterile swabs. There’s also a lot of time spent writing up all this information in our reports and other paperwork. If I worked in DNA or ballistics or toxicology, I would probably spend all day in the lab doing those types of analysis. So it depends on where you work, what services they provide, and what your exact position is. I hope that helps!

Hi what job can i do in forensics that does not require pure math

Asked by Lamecia over 5 years ago

I don’t know what you mean by pure math. Most crime scene work, fingerprints, tool marks, serology, might need regular adding and subtracting, but I don’t know of any field that uses calculus or algebra. DNA analysis uses a lot of statistics and ballistics and traffic accident investigation might use physics and geometry. But those are the only examples I can think of.

Best of luck!
