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.

How to chemically distinguish between an original hand-written signature and a printed copy (the one that is scanned and then printed)

Asked by rixy about 8 years ago

I'm sure document examiners could do this fairly easily but I don't know exactly how. I would guess that alternative light source (like infrared or ultraviolet spectrums) could show that there is no difference between the signature and the rest of the document. Or I believe thin-layer chromatography could show that the chemical makeup is the same. A Questioned Document Examiner could tell you much more.

As a forensic scientist, what problem have you found that lead to unreliability of forensic science? Any possible solutions?

Asked by yubing over 8 years ago

"Unreliability of a science" is pretty a broad swipe, so I don't have any idea what you're referring to. Any line of work--government, plumbing, brain surgery--can be unreliable if the people doing the work are undertrained,overeager, arrogant or lazy.

I am attending Pace University this coming fall with a degree in Forensic Science, any advice for a soon to be Forensic Scientist?

Asked by ssosiak1 about 8 years ago

You can't go wrong with a lot of science classes. When I was in college they didn't have courses specifically in forensic science, so that wasn't an option. And different agencies will have different requirements, so you might want to go online and check out the different vacancies to get some idea of what requirements are out there. You can also call labs you're interested in and ask, that way you get to 'meet' some people too.

What type of personality do you think would make a person well-suited to this type of work?

Asked by Violet about 8 years ago

See above.

On a scale of 1 to 10 how certainly can you look at two photographs and tell whether they are the same individual? Like to show you the photos. Thanks.

Sorry but I am not trained in facial recognition and I am notoriously bad with faces. My husband teases me about it all the time.I'm sorry I couldn't help!

Can extensive bruising be caused by pushing someone with the palm of the hands on the chest area

Asked by Jay about 8 years ago

I'm not a doctor but I don't see why not. If the flesh and muscle is being crushed between the ribs and the person's hands, that would have to cause damage. Sometimes CPR can cause cracked ribs.

I was wondering if the dna from different sources are the same, for example is the dna the exact same in sweat, hair, saliva etc? I ask because I once saw a movie where the criminals threw hair over a crime scene, ruining all the DNA?

Asked by Lisa Fan over 8 years ago

Your nuclear DNA is the same in the skin cells holding your hair in place, your saliva, your blood, your skin, your bone marrow etc. Your friend's DNA is of course different from yours, but the same in their saliva, their blood etc. The criminals probably threw someone else's hair around the crime scene so it wouldn't match them.
