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.
That’s an excellent question, that unfortunately I can’t answer. We have the OBTI test that can confirm blood is human, but beyond that…I don’t know if there are alleles that both animals and humans share that might show up in the average DNA analysis. Even if animals have some alleles that are the same as humans, if those aren’t the alleles looked for in a DNA test, then it wouldn’t affect things. But if they are, then I don’t know if scientists have a way to distinguish them. Sorry I can’t be more help!

We can compare footprints just as finger or palm prints, but there isn’t a database of footprints so you would have to have standards of the suspect’s feet. Otherwise I don’t know what you mean by ‘looked at.’ Everything is looked at, in a sense—there’s ballistics, fibers, bloodstain patterns, arson evidence, toolmarks, video and photo analysis, paint, glass, etc. and etc.

Could you clarify that question? I'm not sure what mean.

I have no idea--are you referring to utility companies marking gas lines, etc? My agency has some flags but we haven't used them recently. I suspect if an agency uses different colored flags it might be some internal coding that they use. Sorry I can't be more help.

The 6" sub is too small and the 12" is too big. Why no 9-inch sub?

Is there a stigma against sushi restaurants that have non-Asian chefs?

Are you pressured by administrators to pass kids that aren't ready yet?
I’m not sure what you mean. Do you mean how does a forensic scientist advance in their career, or what scientific advancements have been made by forensic scientists?

Job requirements depend on the job. Requirements might range from a HS diploma to a PhD. Check the websites of forensic professional organizations (IAI, AAFS, pathology or other disciplines) for job vacancies. I like the variability of the days.I dislike the hours, which can be unpredictable, and require being ‘on call.’

Unfortunately, no, I cannot. I've never worked in toxicology. Sorry I couldn't help.
