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.

What courses did you have to take in college in order to study forensic science?

Asked by hello my name is makiya mcqueen and i am a student at booker t washington magnet high school. I am currently taking a career preparness course and I am very interested in forensic science. I would love to ask you a few questions for my Career investigatio over 6 years ago

Sure, email me at lisa-black@live.com.

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 about 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.

Hey got another question what skill do you need to be a forensic scientist

Asked by Sara over 6 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. 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. Good luck.

How can you prove a controlled substance that was collected from highway isn’t contaminated

Asked by Julie over 6 years ago

It depends on what you're talking about--was what contaminated with what? Lots of things can be contaminated with things without results being affected. Take blood, you can mix blood with paint or dirt or maybe oil or types of soap and that won't affect the DNA profile. If you mix it with bleach or other blood, it will. So if you had, say, heroin, and it gets mixed with fingerprint powder or cotton fibers, it's still going to test as heroin. If you mix it with cocaine, maybe it won't. (Controlled substances are not my field.) So 'contamination' is not a one-size fits-all word.

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 over 6 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.

Do you feel that the junk science portrayed on TV makes it more difficult for you to give successful evidence in court?

Asked by Marcel almost 7 years ago

That's called the 'CSI Effect' and it can be a problem for juries to have unrealistic expectations. One instructor described it as "Juries don't know as much as they think they know, but they really do know a lot more than they used to know."

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 about 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.
