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.

This is for my forensics class. Was there a case that took you longer than expected, or was very easy to solve?

Asked by TERENCE L SMITH over 6 years ago

Wow, that's kind of hard, possibly because we in forensics don't 'solve' cases, the detective does. We provide them the information that hopefully solves or helps to solve the case. Some that took a surprisingly short time: we had a would-be rapist drop his wallet at the scene. I recently had a burglary/arson/car theft in which I had some decent fingerprints, but they didn't match anyone in our city database. The detective had no leads at all and no idea where the car was. Then as is routine I checked the prints against the neighboring city's database, and got a hit, they questioned the suspect and he confessed. In my small town we often have the killer waiting at the scene and telling us that they did it. However, after sitting in jail for a while they may decide they were justified, so the legal trial may not even begin until 2-3 years later. One that took longer: we had the brutal double murder of a woman and a young girl in 1989. Despite a copious investigation of every friend, acquaintance, fingerprint or hair involved, no leads. Then two years ago a man was arrested on a relatively minor charge and his DNA was searched and hit on the unsolved murder. Hope that helps!

Can you extract DNA from human poop?

Asked by Jessica about 7 years ago

Yes. I don’t know if it’s actually from the poop or from the skin cells sloughed off on it, but you can.

How much methamphetamine would it take in a body that was submerged 4 two weeks, for an ME to consider it intoxicated? drowning with environmental hypothermia, contributory cause: methamphetamine intoxication

I’m sorry but I have no idea. I’ve never worked in Toxicology.

I made a cast of a boot I found in dirt. When it is dry and I collect it as evidence, what kind of bag do I put it into? A large paper bag, a plastic Ziploc bag, or another type of container?

Asked by Sam about 7 years ago

Large paper bag. Casting agents usually warm up so that might create moisture inside a plastic container or bag. A cardboard box might be good as well to give it enough support to keep it from cracking.

What is the next step from secondary school in order to become a forensic scientist ?

Asked by Maria over 7 years ago

Go to college and major in forensic science or one of the natural sciences. Best of luck!

I'm studying about fingerprint patterns and phenotypic variations between parents and their kids. Which of the patterns are dominant/recessive? How can there be different patterns on each finger?

Asked by Liza over 7 years ago

Fingerprints develop randomly as a child is moving around in the womb before birth, so they are not dictated by genes. That said, there can sometimes be vague similarities among family members (like having radial loops, all arches, or whatever). There are three patterns, loops, whorls and arches, and you can easily have some of your fingers have loops and then a few have whorls, or they can be all one type, or any combination.

I am busy studying Forensic DNA and srtuggle with the following questions:
consequences of contamination collecting DNA

Your assistance would be appreciated.

Asked by Lindi Steyn over 7 years ago

Contamination may make it impossible to get a DNA profile, or the profile might show a mixture. It will not cause a profile to look like someone else's DNA. Or it may have no effect at all. It depends what is contaminated with what.
