A Madison teenager is accused of using a sledgehammer to break the wrist of a panhandler Sunday afternoon. The suspect’s girlfriend was going to give the panhandler two dollars, but she says 43-year-old Luis Estrada grabbed additional dollar bills out of her hand when she pulled it from her purse. The girl says she spotted a knife up the man’s sleeve, so she decided to leave and tell her boyfriend. He returned to the parking lot carrying the sledgehammer, telling police he was going to try to get his girlfriend’s money back. When Estrada pulled his knife, witnesses called police. Arriving officers found him with a broken wrist and the teen had left the scene. His name hasn’t been released.
