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'm sorry to hear about your brother. Unfortunately I have no idea how much blood there should be, you'd have to ask a pathologist, but from my experience I can guess it would depend on two things--what kind of surface was he on--concrete, tile, carpet, dirt? Also, how long the heart kept pumping after the injury. I have seen gunshot victims where they barely bled at all, and others were completely soaked practically head to toe. So there are a number of factors that will affect this.
Share Answer: 
I would try an alternate light source, UV or IR light or even white light with colored filters. That might make it more visible. Other than that, I don't know, sorry. You'd have to ask a document examiner, they might have more techniques for working with paper.

Please see earlier answer about convicted felons. But as far as I know it would probably depend on the kind of crime, whether it was a misdemeanor or felony, etc. Many juvenile records can be sealed or expunged as well, so that process could be worth checking out.

No. There is no time stamp on DNA, so far as I know.
