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.

Is there technology that you use in your lab or technology that you have heard of that you find interesting?

Asked by Renee over 11 years ago

I'm very interested now in phone number 'spoofing' that the telephone scammers use to call us, but the technology is a little beyond my ken. Actually a lot beyond my ken. I have a co-worker who could explain it but we never have time.

my ex husband put tramadol to his Sprite drink and personally sent the specimen to the forensic lab on Aug 24; which was as dated as Received by the lab but the label in the specimen bottle was Aug 19.
My question is what was the time lapse? help

Asked by Clarity over 10 years ago

I'm sorry but I have no idea. You'll have to ask the lab. I'd love to know myself--I'd also love to know why your ex drugged his own drink and then paid to have a lab analyze it.

What is the first thing you look for at a crime scene?

Asked by Lilly123 over 10 years ago

It depends on the crime, but in general I guess you look for how the perpetrator got in, how they got out, and what they disturbed while they were there. Then I look for what we could get information from (such as surfaces that they had to touch that are smooth and glossy and might have prints, whether they left blood or bodily fluids behind that could be tested, whether they wrote something or used something that could point to their identity, etc.).

what technologies do they use for fingerprinting identification

Asked by nikki about 11 years ago

There are numerous techniques for obtaining fingerprints from surfaces--black powders, colored powders, alternate light, superglue, dye staining. Once you can visualize the print, comparing one to another is done by noting all the information (where ridges end, divide, form a dot, have a scar, etc.) in one pattern and comparing it to another print's pattern. This can be done by a computer so that thousands to millions of prints can be searched quickly, all day, every day, all over the world, but is always confirmed by human beings. Despite what you see on TV!

could you please answer these questions for a project i am doing about career opportunities
a. Describe the working environment
b. Are you working with others or independently working?
c. Does the career involve working in a lab, with people or both

Asked by jejeh about 10 years ago

a) I work at a police department. We have a small lab with equipment for processing for fingerprints and the rest of the office is regular office stuff--desks, computers, supply cabinet, coffee machine.We work mostly days, with someone on call tonight. b) Both. I work on my own for most call-outs and working on pieces of evidence, but for larger cases then we work as a team. c) Both, again. We have a lab but I probably spend only 5-10% of my time, on average, in there.

Can an angry woman use an old pair of underwear to smear dna before doing a rape kit?

Asked by Janet about 11 years ago

See next question.

Writing a novel: How long could dead bodies go undetected in an air conditioned storage unit? Assuming the people who leased it paid in cash and were unattached to their location (so basically no one is looking for them).

Asked by WriterGal about 10 years ago

I'm sorry I can't give you any concrete timelines (a pathologist would know better than I) but I would think at least a couple of days. Air conditioning would definitely make the smell more tolerable than no air conditioning, but still storage units usually have just enough A/C to keep high heat and humidity from causing mold or causing problems with electronics. That's not the same thing as refrigeration. It might also depend on how close the bodies are to the door. People walking by might catch a whiff of something bad but assume that an errant mouse or cat somehow died inside. Thinking that, passers-by might be reluctant to open the door to someone else's property. The storage unit owners, even seeing it unlocked, might try to at least contact the client first, maybe calling the home and the guy's cell which of course he's not answering. Honestly you could probably make it anything you wanted--if you want it discovered quickly, put the unit at the front of the property or give it a fussy neighbor client who visits that same week. If you want it to be a long time, put it at the rear of the property where no other clients visited their units and all units lead to an outer door that didn't show any signs of damage (because both victims and husband entered with their assigned passkey) so the storage unit employees never had a reason to enter to notice either a smell or an unlocked unit. Good luck!
