Cops: Man jailed because he "felt like killing" kills again

PHOENIX - 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, too.

The Maricopa County Sheriff's Office says 27-year-old Andrew Ward, who was already behind bars, was re-arrested and booked for the Wednesday-night killing of his cellmate, Douglas Walker.

The Sheriff's Office says Ward immediately admitted to detectives that he had choked and beaten Walker, adding, "Ward told sheriff's detectives that he had no regrets for the attack."

Authorities say Walker, 33, was stabbed in the eyes and throat, and that 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 his half brother Austin Tapio. In that case, 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."
