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.

Which, in your opinion, is the most effective in solving crime on a daily basis: DNA analysis, Fingerprint analysis or Luminol (or other) spray testing?

Asked by Eliza over 5 years ago

Luminal and dye stains just enhance or show you where things are, like blood or fingerprints. DNA analysis and fingerprint analysis are equally effective, so you use what you have. You might have DNA at a crime scene but no fingerprints, or vice versa. We don’t get a choice of what’s left at a crime scene, so we have to make the most of whatever is there. Given that, whatever is the most effective is whatever gives you information relevant to the crime. Say there’s a smear of the victim’s blood on the suspect’s shirt. The suspect tells police he found the body and tried to administer CPR. In that case, the DNA is very much there, but useless to solve the crime. If the suspect says he never met the victim and the same shirt is found in the suspect’s closet , then that’s very relevant to solving the crime.

What training did you need and experience? Police academy, collage, trade school, etc? Did you get straight into this position or did you have to work up from somewhere?

Asked by David over 5 years ago

Again, titles and job requirements aren't uniform, so the only way to know is to call the crime labs in your area or whereever you might be interested in working and ask them. At the coroner's office we had to have at least a bachelor's in a natural science (this was before they had forensic science majors). At the police department where I am now, they only require a high school diploma but you get more points in the interviewing process for having a four year degree, so we all have one. You can also go on the websites for professional organizations such as the American Academy of Forensic Sciences and check out their job vacancy postings and see what the various positions require. Good luck.

Assume a swimming pool on a yacht was filled with regular tap water and chlorine. A person drowns in the pool. The body is dumped over board and found within hours. Could lung water be tested chemically to help discern the true facts?

Asked by PT O'Neil about 6 years ago

As far as I know that is possible. Whether a medical examiner’s office would actually test the water in the lungs in a case of apparent drowning is another matter. There is also the possibility of ‘dry-drowning’ in which the throat closes and no water gets in the lungs. A pathologist told me once that drowning is sort of a ‘negative diagnosis’ in that, if no other cause of death presents itself and the person is found in water, then drowning is assumed. Sorry I can’t be more help!

What is the correct procedure to gather DNA doing a mouth swab and if it's not done correctly is it considered contaminated

Asked by Britni over 5 years ago

I'm sorry, I was sure I answered this long ago! Collecting buccal swabs is very easy--they come in a kit with everything necessary plus instructions for rubbing the swabs on the inside of the mouth and then packaging. Anyone could do it. I've never heard of a case where it was considered contaminated.

How is it determined that rape occurred after death?

Asked by JODI about 6 years ago

That’s an excellent question that I”m sorry I can’t answer. You will need to ask a pathologist. Sorry I couldn’t be more help!

Can we make a profile of a suspect (skin color, eye color, etc.) from DNA? If not, why not?

Asked by Mrs.McGurkin about 6 years ago

I actually don't know. I haven't done DNA analysis in 20 years so I don't know all the details of what analysis can show. Sorry I can't be more help!

Hi do you know about Forengsic’s regarding suicides?

Asked by Linda over 5 years ago

That’s a very broad question. What specifically do you need to know?
