So how could a man be dick-punched to death in a locked hotel room, while holding a cigarette, without making a sound?
But Wait, It Gets Weirder:
There's no real way to put this gently: Ed Fleniken was shot in the scrotum.
The cops were stumped, so Fleniken's family called in private investigator Ken Brennan. Now, one of Ed's neighbors did hear something odd: a loud crack, like a gunshot. Brennan started sniffing around, and managed to find a small bullet hole in the wall between the rooms, cleverly concealed with what turned out to be dried toothpaste. The electricians in the other room had been drinking, and one of them, Lance Mueller, fired a shot which went through the wall separating their room from Fleniken's. The electricians thought they'd "heard a cough" from the other room, so they figured that the occupant was alright, hastily masked the hole in the wall with what they could find (hence the toothpaste), and took their party to a bar, all without thinking to check on Fleniken.
Unfortunately, the noise they heard was less of a cough and more of an "Oh shit, I've just been shot in the balls" death rattle. The bullet went through the wall and hit Fleniken square in the sack while he was lying on the bed watching Iron Man 2 (a slightly less painful experience). It entered his body and ricocheted up through it, causing massive internal injuries, until finally lodging itself in his heart. Meanwhile, the soft skin of his scrotum swelled and folded around the bullet hole. Seeing no entry wound and having no reason to assume there was one, the coroner didn't bother looking for a bullet. And thus ends the mystery of the Deadliest Dick Punch.
