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.

Why don’t they let civilians interview suspects?

Asked by Jessica over 5 years ago

Because that's not our job. That's the detective's job. They're in charge of and responsible for the investigation.

Have you ever worked a case that was cold?

Asked by Seth over 5 years ago

Yes, certainly. I didn't manage to find the one piece of evidence that solved the whole thing, but I have worked on several. In my department a double homicide finally broke open after 30 years: https://www.news-press.com/story/news/crime/2020/10/01/joseph-zieler-suspect-two-cape-coral-homicides-seeks-dna-expert/3584935001/

Since my finance passed away a month ago and there's been something eating at me now and I don't want anyone to think I'm going crazy. I found him on the floor but how can his legs bend perfectly and his knees
directly on top of each other perfectly

Asked by Shell over 5 years ago

I’m sorry for your loss. What was the cause of death?

Why do you delete so many questions?

Asked by Terry over 4 years ago

Why do you post questions that need to be deleted? Most people have better things to do.

Also, is it possible to specifically detect that the DNA is from saliva and nothing else?

Asked by AJ about 5 years ago

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

I had crash some OLA 2.5 pills with olanzapine 10 mg tablets together and had kept it. Just few weeks back some police officers came to my house n found it. They tested it with forensic and it came back as heroin.
Please can you explain why

Asked by Malvin over 5 years ago

I’m sorry but I can’t. That’s a question for a toxicologist. I don’t know anything about drug chemistry.

how do finger[rints get on things, does our fingers leave fluids when we touch things, or we just leave a print on existing dust?

Asked by rekhab almost 5 years ago

Sorry it took me so long to get back to you!

Yes, fingerprints are impressions made by the oil and sweat on our fingers. If a surface is very dusty, we take away dust on our fingers instead of leaving prints on the object. It will look like fingerprints should be there because there will be finger marks in the dust, but actually we just removed dust.

Hope that helps!
