A Mesa teenager accused of killing his girlfriend's mother has been sentenced to 22 years in prison after reaching a plea agreement with prosecutors.
Maricopa County Superior Court announced Friday that Judge Joseph Welty sentenced Braden Rockriver for second-degree murder and disorderly conduct.
Rockriver must also serve five years of supervised probation for assault when he's released from prison.
Police had alleged that Rockriver took his father's gun from a closet and went to his girlfriend's house in August 2011 intending to either kill himself, or kill his girlfriend and then commit suicide.
After a struggle, police said the gun discharged and the girl's mother, 42-year-old Denna Strebe, was shot. She was later pronounced dead at a Scottsdale hospital.
Rockriver had fled but was captured two hours after the shooting.
