((OOC: Works for me. Everyone can feel free to put a note under each letter posting above with what fingerprints are on them as we go through dusting them. We're currently doing envelope 1 in the list above. If you're L, Light or Mikami and want to put "young small/medium build adult male" prints anonymously, if you don't think the prints could be differentiated well, go for it. Though Light and Mikami have made sample prints, so you might have to make a good case to sheep_dog as to why they can't be determined; examples could include trying to fake L's holding style, etc.
If there are NOT fingerprints on an envelope and your character has touched one or more envelopes (I'm pretty sure they've all touched at least one one), drop sheep_dog a line saying why you're not announcing fingerprints here.
This doesn't apply to Ryuk who can probably touch things without fingerprints, due to a lack of metabolism. Unless he wants to leave prints, I guess. Whatever floats your boat there.))
