PHOENIX -- A teen who pleaded guilty to shooting and killing his girlfriend's mother last year has been sentenced to 22 years in prison.

Mesa police said Braden Rockriver, who was 16 at the time, showed up at his girlfriend's home in August 2011 with the intention of killing her and himself.

Instead, police said Rockriver shot her mother, Denna Strebe, in the head after he forced his way inside the family's home. Strebe's husband, son and nephew were home at the time and heard the shot.

Strebe's son struggled with Rockriver and her husband was able to get the weapon away from him. Rockriver then fled the scene.

Strebe's husband discovered his injured wife in the laundry room.

Rockriver was charged as an adult.

Per a plea agreement, Judge Joseph Welty sentenced Rockriver to 22 years in prison for a second-degree murder charge and 1.5 years in prison for disorderly conduct. The counts will run concurrently.

When Rockriver is released from prison, he will serve a term of five years of supervised probation for assault.
