The couple Wednesday was reportedly arguing in north Houston on Langwick when police say the girlfriend got into a truck and her boyfriend pulled out a gun and fired a shot at her. He missed and she backed into him, running over his leg.
It's not clear what sparked the fight, but when police arrived the boyfriend told them to call his wife.
They were both taken into custody, but the girlfriend was later released.
Police held the boyfriend on a parole violation for having a weapon.
