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.

Thanks for your answer! I have 2 more q's. 1) Is it possible for me to contact you more privately e.g. email, where I can ask more questions in detail? If not, 2) in your opinion, what piece of forensic technology/method helps you the most as a CSI?

Asked by Kate Flynn about 6 years ago

Sure, you can email me at lisa-black@live.com.

What we use the most is a camera, and after that a tape measure (to make crime scene diagrams...99.9% these tell us nothing significant, but there could be that rare exception in terms of court testimony).

What is the most helpful to me is our fingerprint database to identify the unknown prints collected from crime scenes and evidence.

My son died in a car accident. They took him to hospital, then morgue. 3 days later they did blood tests and said he was over the legal limit for alcohol. Is it possible that the numbers are wrong because of the time lapse. Thanks.

Asked by Meho1979 over 6 years ago

I'm so sorry for your loss. They most likely drew the blood right away, and tested it three days later. As far as I know that would not affect the results--bodily fluids are usually not tested immediately since the M.E. or coroner's office sends the samples to a different location for testing. Blood for alcohol testing is collected in special gray topped tubes for that particular purpose, designed to keep the results accurate. Again, I'm sorry for your loss.

Why do you think so many people on this site want people to give them the answer they wanna hear instead of the truth or your (or whomever their asking) opinion? I mean they already told them selves so whats the point?

Asked by Walker asks folks over 5 years ago

I don't get that impression.

Have you ever been emotional with the cases you have worked on?

Once in a great while something will catch me when I’m not expecting it. But very rarely.

An author recently solved the question, 'Did Van Gogh cut off his entire ear, or just the lobe(?).' She found his physician's drawing and it shows the entire ear cut off. Can someone really do that? More likely sliced off by Gaughan's fencing sword?

Asked by PT O'Neil over 6 years ago

As far as I know it’s certainly possible to cut the entire ear off, but I would guess it would be difficult to do accidentally or in the heat of battle without causing other injuries to the face. But that’s entirely a guess on my part. I don’t know more than the basics about either Van Gogh or Gaughan or the incident. Sorry I can’t be more help!

Recently, one of my daughter's friends was dosed with Visine eye drops presumed to be in her drink. Malicious activity? A date rape attempt? Is there a way to test for Visine in a drink, or in food?

Asked by Bill over 6 years ago

The perpetrator could be imitating a scene from the movie “Wedding Crashers” in which they put Visine in a man’s drink to give him diarrhea and vomiting. However Google tells me that’s not what it actually does, it can cause drowsiness and can be dangerous. So the motivation depends on whether the perpetrator knew what the actual effects would be or not.

As far as detecting it, it’s apparently in the imidazole family which includes histidines, so perhaps a chemical lab could detect it or some compenents of it. That would utilize thin layer chromatography and I don’t know how many labs actually do that any more—but I truly have no idea where or how or if a lab could test for it since I don’t have much of a background in chemistry, sorry!

Hope that helps.

I'm going to be graduating high school in a few months and I'm looking to do forensic science, mostly leaning towards biology and examining. I want to know if going to a FEPAC school really matters.

Asked by Morgan almost 7 years ago

I'm sorry but I don't know what a FEPAC school is.
