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.

How is it determined that rape occurred after death?

Asked by JODI over 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!

How did your knowledge of bloodstain pattern analysis help you to secure convictions in past experience?

Asked by Jason Tulanda about 6 years ago

In my personal experience, I have only testified to bloodstain pattern analysis once, and it didn’t really tell anything significant about the case because there was blood everywhere, and the fingerprints in blood weighed more than the patterns.

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 almost 6 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.

I know they use interrogation techniques, polygraphs, and have experts who recognize truth and deception. But do and could someone use hypnosis?

Asked by DJ over 5 years ago

Supposedly, but I don’t know of any cases personally.

A Man is found dead near rail track falling from a train. Can a forensic expert say whether he jumped or accidentally fell or pushed by somebody from train?

Asked by Maria Rose over 5 years ago

I see that on TV all the time but I have a hard time believing it. But I don't know personally. Sorry!

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 about 6 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 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.
