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.

How often do homeless people intentionally try to get arrested? I heard they do this because the shelters won’t take them if they are on drugs among other things so they commit crimes in front of cops to have a place to sleep

I wouldn't be involved with cases like this so I don't know. In my experience with homeless camps the people are usually not too cooperative and don't want to leave, so I haven't seen this happen.

I had crash some OLA 2.5 pills with olanzapine 10 mg tablets together and had kept it. Just few weeks back some police officers came to my house n found it. They tested it with forensic and it came back as heroin.
Please can you explain why

Asked by Malvin almost 6 years ago

I’m sorry but I can’t. That’s a question for a toxicologist. I don’t know anything about drug chemistry.

If a person is hung on their knees, when cut down and laid on the back with the knees/gegs still stiff and bent, can the blood still pool to the back?

Asked by TK almost 6 years ago

That’s really a question for a pathologist, but apparently lividity develops before rigor, so it shoudn’t shift much after rigor has set in. However that can vary depending on temperature and physical/medical conditions. Blood will pool following the law of gravity but if the legs were bent, restricting the blood vessels, then it might pool in the torso. Sorry I can’t be more help.

Can a fallen fake finger nail show bite mark?

Asked by Aj over 5 years ago

I don't see why not, it's rigid and would hold a shape. It's a very small item and somewhat brittle, though. I would think it would be tough to bite all the way through one. You'd probably be better off swabbing it for DNA of the biter.

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 is the cost to a criminal defendant to have a print run through the FBI's AFIS system? Has that cost remained the same from 1999 through the present?

Asked by MsM almost 5 years ago

I'm sorry but I have absolutely no idea. I didn't know there was a cost. I would have guessed that their attorney could request a court order to do so from the judge and the police agency that has the print would take care of it, but I really don't know. Sorry I can't be more help.

Did you have to get pepper sprayed and tased in training?

Asked by Ashlyn almost 6 years ago

Our police officers do, but I'm a civilian forensic specialist, so I didn't. (I also don't carry a gun, don't interview or arrest people and make a lot less money.)
