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.

s it possible to determine trajectory that a gun was fired, if so, how?

Asked by Noah B almost 8 years ago

At it’s most basic, a trajectory is just geometry. If you can find two fixed points then you can draw a straight line between and beyond them.

Hi. Does the crime scene investigator lead the investigation? or does he collect the evidence and analyse it and pass it on to someone who leads the investigation/ interviews witnesses/ searches for the perpetrator etc? I want to work in field

Asked by Justyna almost 8 years ago

Usually, as far as I know, the detective is in charge of the investigation. The CSI doens’t work for them but is there to provide technical support and advice, but ultimately, the detective has the final say. And unlike TV, the detectives are interviewing witnesses and deciding who to arrest. Best of luck!

Can the fingerprints of a living person be taken off a dead human body, namely the skin of the corpse? If so, what are the easiest places for that?

Asked by R-Mod over 7 years ago

Yes. It's not common, but prints have been lifted using superglue or the more recent RTX. The best areas would be those that are smooth, clean and largely free of hair.

I have a niece that wishes to be a forensic scientist. She did not have the best grades and she is struggling trying to get her AA degree from a 2 year community college in forensics. She now has a baby. What would you suggest?

Asked by mikeruth12 over 7 years ago

She should try to get an internship with a local agency--city, county, state police or medical examiner's. Practical experience will count for a lot. However much depends on what kind of forensic scientist she wants to be--does she want to do crime scene work, in which case most of the training is on the job, or does she want to work in a lab, in which case she'll probably need at least a BA in biology or chemistry. She can check forensic organization websites and government websites for job vacancy postings to get an idea of what the job requirements are. She might also check out entry level positions. At our department we have PSA--Public Service Aides, a paid position that's basically a step between community volunteers and sworn officers. They do more cop-type things, but will make contacts and learn a lot. They do things like direct traffic at accident scenes, take burglary reports and process scenes for fingerprints. She might also want to consider that forensic positions involving crime scene work often have unpredictable hours and sometimes overtime, which might be difficult to juggle with child care arrangements.

Considering gunpowder residue, how is it possible for someone to get it on their hand after simply firing a gun?

Asked by R-Mod about 8 years ago

Gunshot residue can actually refer to two things, gunpowder that flies out of the barrel with the bullet and can land on the victim, and primer residue that can leak out of the back of the bullet cartridge and spray out onto the shooter's hand. But it can also get on the gun or nearby surfaces or people so presence of it on hands does not prove someone fired a gun, and it can wipe off easily so absence of it doesn't prove they did.

If a right handed person shoots himself in right temple with a 9 mm weapon while in a seated position in floor with back resting against bed and head slumped to his left, where is weapon likely to be found?

Asked by Jeannie almost 8 years ago

I would guess in his lap or to his right, but it's impossible to know for sure, since you cannot know exactly how the body was positioned or how powerful the load of the bullet might have been.

How long does a blood sample last taken to verify THC content in the specimen? I'm still waiting for results from over 7 months ago.

Asked by Gregory over 8 years ago

I don't know, but it could depend mostly on where the sample was sent and what their backlog is. Some state labs might have a bad backlog. It could also depend on how they prioritize samples.
