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'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.

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

Asked by Sara almost 7 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.

If you were given a 20GB hard drive that had been used to image an 8GB USB device and
found during analysis that more than the 8GB image was on the disk, what would this
indicate? How would you then proceed?

Asked by MK almost 7 years ago

Sorry, but I’m not trained in digital forensics. I have absolutely no idea.

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

Asked by Amyleigh73 over 7 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!

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 (or where) can I get someone to review an autopsy for mistakes or inconsistencies, if corruption is suspected from the investigative agency that was present, and influential during the examination?

Asked by Lina almost 7 years ago

You would need another forensic pathologist to review the work of the first forensic pathologist.

Best of luck.
