The gunman, Joey Demello, 25, is believed to be the ex-boyfriend of Ashlee Saldana, who was staying at the house that night. After the shooting Demello took Saldana from the home against her will.
Officers later found Demello's body at a trailer park near the California-Nevada Border. Investigators said he shot himself. Saldana was found near the scene but was not hurt.
Officers said Demello was on active parole.
