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.

Something about hydrocarbons

Asked by Junz about 8 years ago

But what sample were they testing? What piece of evidence were they analyzing in the gas chromatograph?

A criminal stabbed to death two victims and then inflicted wounds upon themselves The killer's shirt was covered in blood. Is it possible to determine that one victims blood was on top of another persons blood? Can they tell who was stabbed 1st or 2

Asked by Chunky Monkey about 8 years ago

As far as I know, no. The DNA tests of the shirt will just show a mixture of the victims, so that the analyst would only be able to say the blood could have come from these two or three people--in other words there are no alleles that definitely couldn't have come from those three. But because it is a mixture, they can't say it did come from these three exact people. And they couldn't tell, again as far as I know, which blood was deposited first.

Do you feel that the junk science portrayed on TV makes it more difficult for you to give successful evidence in court?

Asked by Marcel almost 8 years ago

That's called the 'CSI Effect' and it can be a problem for juries to have unrealistic expectations. One instructor described it as "Juries don't know as much as they think they know, but they really do know a lot more than they used to know."

I am applying for a grad. program that allows me to pursue a masters in forensic science and a PhD in Biochemistry. How would this compare to if I acquire a PhD in forensic science instead? Thank you.

Asked by Joe almost 8 years ago

I'm sorry but I have absolutely no idea. You might call the labs at which you'd like to work and ask about the positions you'd like to get, and see what they suggest. They would know a lot more than I would.

Best of luck!

On a lot of TV shows, it's often said that water washed away dna evidence (ejaculate). Is it not possible for some to be left deep inside vagina? (Assuming there is ejaculate). Isn't it like taking a bath; water can't really get into vagina?

Asked by Leandra about 8 years ago

Sorry, but I really don't know. You'd have to ask a pathologist. I imagine it might depend on how long after death the person was in the water.

If I keep a lock of hair in a bottle and it's stored in a humid area, will the hair still disintegrade over time? Thank you!

Asked by :) almost 8 years ago

If the bottle is sealed well, I don't think so. Hair is pretty tough.

Hello Lisa! I am doing a essay on pattern and impression evidence for college. One of the requirements is to email someone who works in this field. Why is pattern and impression very important in investigations? An overall description of your job

Asked by Lyubov Barbin over 8 years ago

I'm sorry but that's a very broad question. What kind of pattern and impression evidence are you talking about?
