Forensic Scientist

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.

Is it true that a females DNA can't be used to trace paternal male lines? How would I trace my fathers ethnicity with him gone and no brothers?

Asked by L.Randolph over 9 years ago

I'm not a DNA expert, but I know that half the 23 chromosomes in a person''s nuclear DNA come from one parent and half from the other parent, so part of the father's DNA would have to be present in the child.

Mitochondrial DNA (which is a different substance entirely, a circular structure present in the cell's mitochondria, whereas nuclear DNA is a double helix present in the cell nucleus) is passed from mother to child without recombining, so only the mother's mitochondrial DNA is present in the child. We test for mitochondrial DNA when nuclear DNA isn't available, like when we only have cut hair or fingernails or old bone to work with.

if dna or other evidence could be reproduced by a 3d printer how would this effect forensic

Asked by viorgateway over 9 years ago

I'm afraid I don't know enough about how 3-D printing works to be able to answer. I can guess that it might be handy for reconstructing items such as shoeprints and tire tracks from photos or scans. Other than that I don't see where making a copy of something would necessarily affect a crime. And as far as I know they haven't reached the point of replicating on a cellular level such as DNA.

I'm not sure who to ask, but could you possibly explain the decomposition process of a shipwreck victim's body after 3 years of being underwater? Thank you for your time!

Asked by Irene about 9 years ago

I'm sorry, I really couldn't. You need to ask a pathologist. Best of luck!!

Is there a license required to become a forensic scientist? If so, what type?

Asked by Violet about 9 years ago

No. Depending on where you work and what you do, your employer might want you to be 'certified' in one area or the other.

Discuss how the following statements can both be true when applied to forensic investigation: “Every contact leaves a trace” AND “Absence of evidence is not evidence of absence.”

Asked by Sara over 9 years ago

Why does this sound like a homework question?

I have a BSc in microbiology. What else do I need to become a Forensic scientist? What are your thoughts on what Master's program I should pursue if any?

Asked by Nix about 9 years ago

Each agency will have their own requirements. The best way to know what to expect is to call all the crime labs in the area and ask what their requirements for various positions are. You can also check websites for forensic organizations such as www.theiai.org and www.aafs.org and examine their job postings. Best of luck!

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 9 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.
