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.

If the song Before He Cheats happened in real life how would you investigate the vandalized car???

Asked by Sherri Karry Katie Perry almost 5 years ago

I would fingerprint around all the damaged areas and the handles, and possibly collect a sample of paint in case the suspect’s keys were found (provided the state lab would do FTIR analysis on a non-violent case). And of course we’d check for any video cameras in the area that might cover the parking lot. And measure the width of the holes in the tires in case the suspect’s knife was located.

Saying that they DID do what ever it is they are being accused of?

Asked by Mike almost 5 years ago

There have been a few cases in which I testified where the defendants were found not guilty, and I was fine with that. In some there simply wasn't sufficient evidence, in one it was clearly self-defense, in two the defendants were charged with murder and I figured it should have been manslaughter. But that's why we have a jury system, and they did a good job.

Also, is it possible to specifically detect that the DNA is from saliva and nothing else?

Asked by AJ over 5 years ago

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

Since my finance passed away a month ago and there's been something eating at me now and I don't want anyone to think I'm going crazy. I found him on the floor but how can his legs bend perfectly and his knees
directly on top of each other perfectly

I’m sorry for your loss. What was the cause of death?

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 about 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.

What majors and minors do you recommend someone interested in forensics to take? Should I major in forensics or something else? And how can one determine which area of forensics they would like to go into?

Asked by Serena over 5 years ago

Titles and job requirements aren't uniform, so the only way to know is to call the crime labs in your area or whereever you might be interested in working and ask them. At the coroner's office we had to have at least a bachelor's in a natural science (this was before they had forensic science majors). At the police department where I am now, they only require a high school diploma but you get more points in the interviewing process for having a four year degree, so we all have one. You can also go on the websites for professional organizations such as the American Academy of Forensic Sciences and check out their job vacancy postings and see what the various positions require. As for determining which area, I would suggest you visit crime labs in the area to see what they do and talk to the people working there. Good luck!

What is the cost to a criminal defendant to have a print run through the FBI's AFIS system? Has that cost remained the same from 1999 through the present?

Asked by MsM almost 5 years ago

I'm sorry but I have absolutely no idea. I didn't know there was a cost. I would have guessed that their attorney could request a court order to do so from the judge and the police agency that has the print would take care of it, but I really don't know. Sorry I can't be more help.
