I can only imagine being shot 22 times with three to the torso... who knows? I’m guessing the torso shot plus the hour he lay dying with no emergency medical help. Sometimes you don’t need to be a medical professional and I think this is one of those times IMHO.
Shoot, you could bleed out with 22 holes in an hour and a quarter, even if none of them were in the torso, especially if you nicked or holed a femoral artery.
