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 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.

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 almost 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.

Hi Miss, I'm a student from Australia conducting a Research Project and my question is 'how have forensic methods evolved through the last 40 years to improve the rates of crimes solved'. As a professional, would you be able to elaborate on this?

Asked by Kate Flynn about 6 years ago

Wow, that's an extremely broad question. I don't know if the rates of crimes solved have been increased greatly--perhaps in some crimes like rape or murder but perhaps not in other crimes like burglary and theft. But certainly the biggest advances in forensics have been DNA and the connectedness of fingerprint databases. Less specific but perfectly valid analyses like pollen, soil, and other trace evidence examination have gone by the wayside. And digital analyses such as the downloading of cell phones and personal computers are helping solve crimes more and more, but then people didn't have cell phones or personal computers 40 years ago so I'm not sure that counts!

I hope that helps!

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 over 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!

How anonymous are people really on the dark, deep, and even on the regular internet? What about websites where people talk about bad things they have, doing, or going to do without signing up or anything?

Asked by Dan over 5 years ago

I'm sorry, but I have no idea. I don't work in digital forensics.

Can I ask you some questions for my novel? I need some things fact-checked. Probably too long to write on here.

Asked by Paula over 5 years ago

Sure! Email me at Lisa-black@live.com.

Wow the person who continues to spam you does not realize is people like him are probably the reason he left. Anymore this site has just been spammers, trolls, people sharing links, people asking irrelevant and quite weird questions. what a shame

Asked by Follower over 5 years ago

I can’t imagine having so little to do. That would make me crazy.
