you really cant say insanity because there must have been some point where he stopped and said to himself "man im tired. I think ill use the hammer instead." then (most likely, i mean you have hammers lying around?) went to his garage/tool shed/ closet and got his hammer, and came back to the dude lying in a pool of blood, and commence to whacking. I mean that takes alot of thought.Beat him to death with a sledgehammer AND a claw hammer. That means the guy had to reach of point of either exhaustion or bordem with hitting the guy with the sledgehammer to put it down and pick up a claw hammer!!! Holy Issues Batman.

kinda wonder if the beating took place in or around the bathroom. seeming what they were fighting over, it seems possible.i keep hammers, knives, and oddly placed rifles laying around in my room, not to consider the rest of the apartment
