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, what is your opinion on auditors?

Asked by Cale over 5 years ago

I don’t know what you’re referring to.

Can a coroner make a arrest? People like to always make the point about a “citizens arrest” but I’m sure you know what I’m talking about.

Asked by Richard over 5 years ago

I don’t really know, but at the coroner’s office I worked at I was told that our coroner was actually the highest law enforcement officer, technically, in the county. She was the only person who could arrest the sheriff if necessary. That never became necessary though so I don’t know how it would actually work.

If a attacker OC sprayed someone and robbed them is there chemical tests to see if the spray that was on the victims face and the Pepper spray on the suspect to see who did it

Asked by Question almost 5 years ago

That’s a good question that I’m afraid I can’t answer. I’m sure there is some way to determine the chemicals used in pepper spray. But this would be affected by a) how long does it remain on the skin before the skin absorbs it and b) most forensic chemistry labs are set up to detect illegal drugs in urine, blood or gastric contents. Identifying any kind of poison or other substance may require equipment or reference databases they don’t have.

Proving it’s the same batch of pepper spray may or may not be possible. I”m not personally involved in this kind of testing, but I can assure you it is not like television. We had a series of cases and wanted to determine the exact composition of drugs with percentages of fentanyl, heroin etc. Turned out while nearly every crime lab can determine if a drug is present, there were only one or two labs in the entire country we could find that could determine percentages, and they charged an arm and a leg. 

Sorry I can’t be more help.

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

Asked by AJ about 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's the best way to highlight and uncover gloveprints left by Nitrile gloves from a surface?

Asked by Richard over 5 years ago

Usually simple black powder will show gloveprints as well as fingerprints. The bubbly sort of pattern they make will be visible.

Since my finance passed away a month ago and there's been something eating at me now and I don't want anyone to think I'm going crazy. I found him on the floor but how can his legs bend perfectly and his knees
directly on top of each other perfectly

Asked by Shell over 5 years ago

I’m sorry for your loss. What was the cause of death?

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!
