First our victim's wife (we'll call her Wifey) is awoken by such a clatter that she ran to the kitchen to see what was the matter, and what to her wondering eyes should appear, but 24 year old Aaron A. Bell beating her husband (we'll call him Hubby) about the head with a "heavy-duty stapler". Wifey joined the fray and pulled Aaron off of Hubby and Hubby ran to the bedroom. Hubby tried to climb out the Bedroom window to get to the porch but he was too drunk (it makes me wonder what was so important on that porch). Hubby fell out of the window and was knocked unconscious. Aaron eventually escaped the grasp of Wifey and went outside to yell at the now unconscious Hubby. Aaron decided to try to run away, but the Boys in Blue used their top notch detective skills and tracked him down by visiting his house.
Now I did a quick google search for Heavy Duty Staplers, and the most common type are similar to the image above. Something with a solid base and a big handle is what the industry likes to refer to as a "Heavy Duty Stapler", and while I don't in anyway encourage or endorse beating on other humans with staplers, I would theoretically encourage you to use a Long Reach Stapler as it would allow you to get a little more muscle behind each swing. Aaron was charged with "misdemeanor battery with a dangerous weapon" but if you attacked somebody with a Long Reach Stapler you would probably be saddled with a felony charge.
