PHOENIX (AP) -- An Arizona man who reportedly told police he killed his 12-year-old half brother earlier this month because he "just felt like killing" is now accused of fatally stabbing a jail cellmate.
The Maricopa County Sheriff's Office says 27-year-old Andrew Ward was arrested in the Wednesday night killing of cellmate 33-year-old Douglas Walker.
The Sheriff's Office says Walker was stabbed in the eyes and throat. He was also beaten and his breathing passages were obstructed by a plastic bag.
Andrew Ward previously pleaded not guilty in the March 12 killing of Austin Tapio. He was arrested after calling 911 from a convenience store near his family's home. The half brother had multiple stab wounds.
Police said when asked why he killed the boy, Ward said, "Honestly, I just felt like killing."
