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 over 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 almost 7 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.

If someone takes their own life by hanging is it common for it to be a double knot?

Asked by Kim about 7 years ago

There’s a wide variety of knots as people tend to use whatever they think will work.

I hope that helps.

Do you watch Law and Order?

Asked by Jimmy over 6 years ago

Not regularly, but I’ve caught many reruns over the years.

if I can send you a picture can you please tell me the entrance wound or the exit wound from the pictures in your experience

Asked by Clu D Wright over 6 years ago

No, you would really need a pathologist for that. Generally, exits tend to be larger than entrances, but it depends on what someone is shot with and where. If the muzzle is very close or in contact with the body, then the entrance will likely be larger than the exit. if the bullet fragments inside, then there might be a small exit. So different factors can affect it. Best of luck to you.

What does it mean if a cadaver had "abundant amount of mud on the hands," if the body was in the water for two weeks and it was swift water for days?

Asked by Lina N Lete almost 7 years ago

‘Abundant’ probably just means the hands were smeared with mud on some parts, not that they had clumps of mud in them. Why it would be on the hands after being in water—some possible reasons might be that the body got hung up in muddy shallows and that’s why it was found, or it was dragged over muddy areas when pulled from the water. As I don’t have any picture of where it was or how it was recovered, that’s my best guess.

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!
