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.

What do you enjoy most about your job? (Sorry for the typo on the last question, it was supposed to say: "(Thank you for your time in advance)"

Asked by Nate over 9 years ago

All the interesting, different, bizarre stories that make up the crimes that have happened that we have to investigate. 

Hi! I'm writing a mystery where the murder weapon is a maduvu, a knife with two antelope horns. I'm wondering what would distinguish the wound to make it unique to that weapon, assuming the victim was stabbed in the chest or back. Thanks!

Asked by katrosswriter@gmail.com almost 10 years ago

Wow, you'd really have to ask a pathologist. But I would assume a stab wound with a horn would look different than one from a knife, more round and uniform. You might also have a sliver of horn break off in the wound. The round wound in the flesh or bone might make a doctor think it came from a bullet at first, but with no bullet found then they might think icepick or something horn-shaped. Best of luck!

Can seman be removed with dry cleaning

Asked by aratliff8 about 9 years ago

I don't know that as a fact, but I would think so. Simply washing with soap and water will take care of it.

Been reading through these with great interest Lisa, I love forensic science! if criminals had time and the area was very small what is the best way for criminals to either erase or cover up there DNA? Thanks:)

Asked by tommy k over 9 years ago

They could try not to leave it in the first place--wear gloves and a hat, and don't cut yourself on the window you broke to gain entry. And wear a mask since you never know who has cameras where in this day and age!

How often did you encounter gloveprints? Can they be wiped? What are the necessary circumstances for them to exist? I'm asking not to become a murderer, but to help make a roleplaying case for people I know.

Asked by R-Mod almost 9 years ago

Not often. Since a glove itself isn't secreting sweat and oils, there's really nothing for it to make a print with until it gets a little dirty or if the surface it's touching is a little dirty.They can be wiped off as easily as any other print.

What are the major responsibilities of your job?

Asked by Violet over 9 years ago

I spend about 90% of my time sitting in front of a computer looking at fingerprints. The rest of the time I go to crime scenes to photograph and process for fingerprints and collect items of evidence. When I was at the coroner's office I probably spent 40% of the time examining victim's clothing, 10% on gunshot residue testing, 30% on hairs and fibers, and 20% everything else. 

What kind of toxicology is needed to produce evidence of poisoning from chloroganic pesticides and illicit drugs from around 16-17 years ago. A trace unknown substances test? Blood, hair, bone marrow . . . sample? Free at a gov. agency? for a guy.

Asked by Glass over 9 years ago

I'm so sorry but I wouldn't have any idea since I've never worked in toxicology. And since my agency doesn't do it either I don't have anyone to ask.
