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.

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.

Have you ever done a case where you did not think the person who did it deserved to be locked up?

How did you handle it?


If you have not. How would you react to that? If you’re asked to do a case but don’t agree the person should be arrested?

Asked by Mike almost 5 years ago

My job isn't like TV--I'm not involved in every single aspect of the investigation. My job is to provide forensic support to the detectives, so in any given case I estimate I know perhaps 20% of the overall information relating to the crime. I don't know what witnesses, victims, suspects have said, what financial or phone records might show, etc. etc. The detectives would probably tell me if I asked, but I'm usually too busy with all the other cases to ask.

Who to arrest and who to prosecute is up to the detectives and the prosecutors. They don't ask my opinion, and in light of the first paragraph, I probably couldn't give them an informed one.

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!

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!

Hello,

How do you go back and re construct the last 24 hours of someone’s life

Asked by Margarita over 5 years ago

I’m sorry but I have no idea. that would be the detective’s job, not mine.

Best of luck!

Was this election stolen from Trump?

Asked by asdfasdf over 5 years ago

What does that have to do with forensics?

So do you pretty much get to do all the fun stuff without as much paper work?

Asked by Rae almost 5 years ago

No, we have lots of paperwork. Lots.
