I guess he pissed someone off to be shot with a nail gun that many times. I would think that finding the mail gun that did this would be rather hard because the nails fired from it are not marked as a bullet from a gun. I think they should find where his last work place was to find what crew he worked with as a way to find a possible suspect.
This is gross, can you think of a worse way to go? Nail guns have always scared me since I saw Lethal Weapon 2...
