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.

I need to know how can I get blood group from old dried blood?

Asked by Mou over 5 years ago

They used to do that in serology, taking threads soaked in the blood and putting them in tiny pools of blood type reagents. I don’t know exactly what the reagents were, sorry, that had never been part of my duties. But if you research old serological techniques you should find it.

Best of luck!

Have you ever almost got fired before?

Asked by Mike over 5 years ago

Not that I know of.

What is the most complicated case you’ve ever worked and why?

Asked by Captain Coke over 5 years ago

I can't think of any one in particular that was the most 'complicated'--many were difficult and complicated for different reasons. Forensics is only part of the whole investigation, so things really get much more complicated for the detectives who not only have to absorb the information we're giving them but deal with victims, witnesses, suspects, documentation, records, warrants and prosecutors. I worked one where the victim had been taken to three different places before the body was dumped and burned, so there were indoor scenes, outdoor scenes, the suspect's house to deal with. Right now we're dealing with one that spans 30 years, so trying to find reports and piece together who did what and when and what, if anything, still remains to be done. And we had one earlier this year that had inexplicable behavior by about 9 different people over three days and all to cover up an accidental death. Hope that helps.

Are there any famous cases in history that involved thin layer chromatography (TLC) that you are aware of? Or any interesting facts many would not know?

Asked by Mike about 5 years ago

I”m sorry but I”ve never used thin layer chromatography. If I had, it most likely would have been to distinguish extracted fiber dyes. As far as I know it’s the only way to determine if natural fibers likely had the same source.

What level math do you actually need and use?

Asked by Elizabeth G. over 5 years ago

It depends on what you want to do. I've always used only basic addition, division etc., for calculating reagents. Accident reconstruction would probably require a bit more and maybe DNA analysis, but I don't really know. Best of luck!

Biggest pet peeve out of co workers? I also heard working at police and sherif departments your lunch is always stolen is this true?

Asked by Mike almost 6 years ago

That's never happened to me at the police department, but then there's only my forensic unit with access to our refrigerator so it's not a problem. But it used to happen in the lunch room at the coroner's office all the time! I injected candy with hot sauce once. That stopped it for about a week.

How do you do a ride along?

Asked by Cale over 5 years ago

Contact your local PD and ask what their procedure is. You will probably have to fill out an application and a waiver. Best of luck!
