A woman admitted that she "liked to hear people say 'ouch'" and that was why she'd been driving around Stevens Point, WI with a blowgun, a slingshot, and a bucket of rocks, zetzing random people with various missiles:
One of the victims reported she saw the dart shot from a pipe sticking out the window of a black minivan. Police pulled the vehicle over at 9:30 p.m. and found a blow gun, a slingshot and a bucket of rocks inside.
Police arrested the van's driver, Paula Wolf, and said she eventually admitted to shooting the pedestrians. She allegedly told an officer that she "liked to hear people say ouch."
