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.

I just graduated with a bachelors in Forensics and I have an interview at a crime lab next week, what can I expect? Will they want to see my transcripts.

Asked by FORENSIC over 7 years ago

I’ve never had someone ask for transcripts at an interview, and I think it would be a little unreasonable for them to expect you to have them with you without warning.It will be generally like any other interview. When they ask what experience you have in forensics be sure to mention specific tests and techniques you’ve done, like superglue, crime scene reconstruction, the AFIS system, etc.

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 almost 7 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!

What is the best way to read the writing imprints left on paper towels or ziplocks without scientific equipment?

Asked by Amyleigh73 about 8 years ago

I would try oblique lighting—try laying the piece down as flat as possible and then hold a flashlight to the side so the light beam travels across the piece instead of down onto it. Adjust the light to where it’s the most helpful. With the ziploc bag you might also put a piece of dark paper inside it to increase the constraint. That’s all I can think of since I’m not an expert in questioned documents. Best of luck!

What are some safety hazards, contamination / degradation hazards and how do u package SEMINAL STAINS A

Asked by Jayleen almost 7 years ago

That's a pretty broad question. I can tell you that for both seminal stains and blood stains, the best way to package one is to let it dry, then place in a sterile paper envelope or bag. Never plastic! Then keep in a dry, cool environment.

Hope that helps.

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 8 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.

Which drug do you think was the most fatal in this report?
Samples are ng/ml
Morphine 220
Tramadol 780
Fentanyl 19

Asked by Cheryl almost 8 years ago

As I’m not a toxicologist, I’m afraid I’d have no idea. Sorry!

If I have a BS in Physics, is that the right path to become a blood spatter analyst or a ballistics expert?

Asked by Trey almost 8 years ago

I think it would certainly be an asset!

Best of luck.
