The U.S. Marshals Service is offering a $2,000 reward for information leading to the arrest of a shooting suspect.  

William Gardner is alleged to have shot his ex-girlfriend several times in the head Monday morning as she sat in a parked car in the town of Winters.

Gardner and the victim, 32-year-old Leslie Pinkston had dated but recently broke up.  

Court records show that Gardner has a history of violence with a spousal abuse conviction in 2011, and was also awaiting trail on charges of stalking and threatening Pinkston.
