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.

How can we detect the GHB from urine sample by LCMS?
Is there any simple method?

Asked by Eman over 5 years ago

I’m sorry but I’ve never worked in toxicology. Sorry I couldn’t help!

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!

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

Asked by Captain Coke almost 6 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 over 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!

I have my first interview out of college for a forensic chemist position. Do you have any tips for a first timer? Are there any questions I should really prepare for?

Asked by MIKE about 5 years ago

Wow, best of luck!! I would suggest you Google the heck out of the facility and find out everything you can about what they do—if it’s a state lab, what kind of evidence they accept from the state agencies. They probably test for illegal drugs, but are they testing the actual drugs seized, or bodily fluids from arrested people, or blood/urine/gastric samples from medical examiners or coroners offices—or all three. If you can’t find the information then that’s a good and reasonable question to ask. They’re sure to ask you what kind of instrumentation you’ve worked with, in class or in an internship, etc.—GC Mass Spec, IR, etc., how much experience and what kind of samples you tested. PS If it’s not posted you might want to ask about hours and/or overtime. They might be 9-5 M-F or they might be 24/7, depending on the size and location.

Best of luck!!

Have you ever did something bad, mean, or inappropriate to a dead body? What is your standard of morals and ethics?

Asked by Dolby about 6 years ago

Quite the contrary, I find myself apologizing to them if I bump into their gurney. They’re dead. How could I not feel sorry for them?Both my department and the various forensic organizations of which I am a member have published codes of ethics to which I have always adhered.
