SALINA, Kan. (AP) — A Kansas teenager who shot and killed his 9-year-old stepbrother during an argument over doing chores will be sentenced in August.

Ryan Velez, who is now 18, has spent about three years at Larned State Hospital after pleading guilty in 2011 to murdering his stepbrother, Kaden Harper.

During a hearing Monday, Velez’s sentencing was scheduled for Aug. 6.

The Salina Journal reports Velez was sent to Larned for treatment after pleading guilty last September to unintentional but reckless second-degree murder. Because he was released before his sentence was complete, he was referred back to district court for sentencing.

Prosecutors said Velez shot his stepbrother on June 1, 2010 at their rural Assaria home when the boys were home alone.
