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.

Would a B.A. in physiology be an acceptable degree for pursuing a career in forensics?

Asked by Abigail about 5 years ago

Any agency can use whatever requirements they want, so some (like mine) require only a high school diploma (but give extra points for advanced degrees, so we all have degrees). Some might require a Bachelor’s in any subject but give more points for forensic training—or not. The only way to know is check their job postings. Best of luck!

How often do homeless people intentionally try to get arrested? I heard they do this because the shelters won’t take them if they are on drugs among other things so they commit crimes in front of cops to have a place to sleep

I wouldn't be involved with cases like this so I don't know. In my experience with homeless camps the people are usually not too cooperative and don't want to leave, so I haven't seen this happen.

I had crash some OLA 2.5 pills with olanzapine 10 mg tablets together and had kept it. Just few weeks back some police officers came to my house n found it. They tested it with forensic and it came back as heroin.
Please can you explain why

Asked by Malvin about 6 years ago

I’m sorry but I can’t. That’s a question for a toxicologist. I don’t know anything about drug chemistry.

If a attacker OC sprayed someone and robbed them is there chemical tests to see if the spray that was on the victims face and the Pepper spray on the suspect to see who did it

Asked by Question over 5 years ago

That’s a good question that I’m afraid I can’t answer. I’m sure there is some way to determine the chemicals used in pepper spray. But this would be affected by a) how long does it remain on the skin before the skin absorbs it and b) most forensic chemistry labs are set up to detect illegal drugs in urine, blood or gastric contents. Identifying any kind of poison or other substance may require equipment or reference databases they don’t have.

Proving it’s the same batch of pepper spray may or may not be possible. I”m not personally involved in this kind of testing, but I can assure you it is not like television. We had a series of cases and wanted to determine the exact composition of drugs with percentages of fentanyl, heroin etc. Turned out while nearly every crime lab can determine if a drug is present, there were only one or two labs in the entire country we could find that could determine percentages, and they charged an arm and a leg. 

Sorry I can’t be more help.

Does gas chromatagraph/chromatagram data always show peaks relative to the solvents used with samples to perform gc/ms analysis?

Asked by Answer Seaker about 6 years ago

That is a great question that I can’t answer! So sorry, but I never worked with a GC or Mass Spec. That was the toxicology department.

Can a fallen fake finger nail show bite mark?

Asked by Aj over 5 years ago

I don't see why not, it's rigid and would hold a shape. It's a very small item and somewhat brittle, though. I would think it would be tough to bite all the way through one. You'd probably be better off swabbing it for DNA of the biter.

I need to write an extended essay for school about an area of my interest. What is a forensic science method which still needs some research. I need to conduct an experiment and form a conclusion from my hypothesis.

Asked by Yusra almost 6 years ago

Arson investigations, bitemarks...though those might be difficult to do experiments on. Best practices for visualizing superglued fingerprints depending on the surface? Genealogical tracing?

Best of luck!
