Forensic Scientist

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.

Do you believe that more could be done to improve dna testing

Asked by kerrie dunbar over 9 years ago

Improved in what way?

Hello Ms. Black, I have two questions 1) can those with a past juvenile conviction enter the field of forensics 2) might you be able to put me in touch with a forensic scientist who would do a informational job interview with one of my students?

Asked by SLP over 9 years ago

Please see earlier answer about convicted felons. But as far as I know it would probably depend on the kind of crime, whether it was a misdemeanor or felony, etc. Many juvenile records can be sealed or expunged as well, so that process could be worth checking out.

You can have your student contact me Via my web site at www.lisa-black.com and I'll try to help!

when i was in third grade i had a chemistry set- on day a relative gave me conc nitric acid; glycerin and some powdered magnesium - i almost got hurt -got lucky- do u think this person meant me harm- i've often wondered

Asked by markboutwell65@gmail.com over 8 years ago

Without knowing you or your relative, I really couldn't guess. Maybe they hoped you'd read the instructions first?

When looking at a murder scene, could you simpky check the body for fecal matter or urine in their groin area to see if that is where the murder took place?

Asked by Quincy over 8 years ago

I think you mean to check for that wherever they're lying to see if the body had been moved?

Well, not everyone evacuates upon death. Also the clothing absorbs most of it, and any that leaks through could also have leaked through after being moved. But yes, that could be an indication that the body had been moved just as bloodstains would.

Hope that helps!

Is a forensic expert allowed 2 make a hair or fiber match based only in the fact that the hairs or fibers were artificially dyed

Asked by Michele about 9 years ago

Unlike what you see on TV, a hair and fiber expert never 'matches' hairs or fibers (except in the case of DNA analysis). We can say they are 'consistent with' having come from this person or this article of clothing in that all the microscopic characteristics are the same or within a group of the same characteristics. Though dyed hair is quite distinctive with the growth since dying and the color so it would be a strong indication that they came from the same person, you couldn't actually put a number on it (like 'there's a one in two billion chance this came from someone else', like DNA). That's largely why hair and fiber comparisons are rarely done any more.

How long does it take to really get a fingerprint match if using all available databases?

Asked by Seeker over 9 years ago

That depends entirely on your digital situation. How big is the database (how many fingerprints does it have to search through), are you searching both fingers and palms, how many servers or whatever can you devote to the task, and have the search parameters been narrowed down, say to only right hand fingers or only the left index. All those factors will affect it so that a search could take anywhere from a few seconds to a day .

If the bar code if worn off of a computer and you are trying to figure out what the bar codes numbers were. How can you get the numbers? Cause where the bar code was before it was torn off. It left a lil bit of the code is visible.

Asked by Laray kirker almost 9 years ago

I would try an alternate light source, UV or IR light or even white light with colored filters. That might make it more visible. Other than that, I don't know, sorry. You'd have to ask a document examiner, they might have more techniques for working with paper.
