January 2011: On Sept. 16, 2010, Officer Rocco Cipriano of the Scranton (Pa.) PD was called to a house on a domestic issue. An adult guardian had seen a 15-year-old attack her 10-year-old sister. The guardian, who had severe heart problems, barricaded himself in his room. Finding the front door blocked, Cipriano decided to enter the house through a window that contained an air conditioner unit. As he pushed out the air conditioner, the girl ranted at him and threatened him with a knife. She stabbed the air conditioner with the knife and broke off the blade. Suddenly disarmed, the girl became much more peaceful. Cipriano convinced her to let him in. Once Cipriano was inside she became more agitated and Cipriano's sergeant TASERed her.
