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 have absolutely no idea.

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.

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

Sorry it took me so long to get back to you!
Yes, fingerprints are impressions made by the oil and sweat on our fingers. If a surface is very dusty, we take away dust on our fingers instead of leaving prints on the object. It will look like fingerprints should be there because there will be finger marks in the dust, but actually we just removed dust.
Hope that helps!

Any agency can use whatever requirements they want, so some (like mine) require only a high school diploma (but give extra points for advanced degrees, so we all have degrees). Some might require a Bachelor’s in any subject but give more points for forensic training—or not. The only way to know is check their job postings. Best of luck!

I can’t speak to this guy’s course specifically, but deception detection training is often offered to detectives and law enforcement personnel. I sat in on a two day course through my department once, just to use in my writing.
