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 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!
Sorry, but I really don't know. You'd have to ask a pathologist. I imagine it might depend on how long after death the person was in the water.
I think that depends entirely on where you live or want to work. If you intend to apply for lab or crime scene work in a large city, then no. If you're going to work crime scene in a remote area with a lot of outdoor scenes and animal activity, then maybe yes. Regardless, an internship at your local forensic facility would be better. If that's not possible, at least call them and ask for their advice.
As far as I know, no. The DNA tests of the shirt will just show a mixture of the victims, so that the analyst would only be able to say the blood could have come from these two or three people--in other words there are no alleles that definitely couldn't have come from those three. But because it is a mixture, they can't say it did come from these three exact people. And they couldn't tell, again as far as I know, which blood was deposited first.

I'm so sorry but I don't know. I'm not trained in digital forensics.
