In this undated handout photo provided by the Maricopa County Sheriff's Office, Maricopa County Superior Court says Braden Matthew Rockriver, 16, is being held on $1 million bond. Police allege Rockriver took his father's gun from a closet and went over to his girlfriend's house Monday intending to either kill himself, or kill his girlfriend and then commit suicide. Forty-two-year-old Denna Strebe was shot inside her Mesa home. It's unclear whether Rockriver has an attorney. His next court date is Aug. 23.
