Thousand Oaks, California: Authorities say a man shot and killed his former wife at a Southern California mall and then turned the gun on himself.

Police say the 33-year-old gunman was taken to a hospital on Saturday. The Ventura County Star newspaper reports that the Los Angeles-area resident is in critical condition.

Ventura County sheriff's Sgt. Eric Buschow says the man went to a store at The Oaks mall in the city of Thousand Oaks and argued with the 30-year-old victim before shooting her.

He says the couple have children, who have been found and are safe.

Buschow says initial indications show that the shooting was a murder and attempted suicide.
