Authorities say a 25-year-old parolee shot and killed a mother and son in Southern California then kidnapped his ex-girlfriend from their house before fatally shooting himself hours later.

Ontario police spokesman Anthony Ortiz says 25-year-old Joey Demello was found dead of a self-inflicted gunshot wound at about 11 a.m. Saturday at a trailer park near the California-Nevada state line after getting a call from his former girlfriend Ashley Saldana. Saldana was found unharmed in the same area.

Police responding to a report of a shooting about six hours earlier found a 21-year-old man and his 48-year-old mother dead from gunshot wounds in their home in Ontario 40 miles east of Los Angeles. Their names have not been released.

Police say Saldana was spending the night at the house.
