PHOENIX – A man arrested in the stabbing death of his 12-year-old half-brother is now accused of killing his cellmate at the Lower Buckeye Jail.

According to the Maricopa County Sheriff's Office, Andrew Ward killed Douglas Walker Wednesday evening in their locked cell where they had been housed together for the last three weeks.

Sheriff's officials said Walker, 33, had been beaten, stabbed with a golf pencil and his head was smeared with peanut butter. Paramedics later determined that Walker's breathing had been obstructed by a plastic bag placed in his nose and throat.

He was pronounced dead at the scene.

Sheriff's detectives questioned Ward, 27, and said he admitted that he had choked and beaten Walker. Ward reportedly told detectives that he attempted to cut Walker's throat with a plastic playing card, stabbed him in the eyes and throat using a golf pencil then stuffed a plastic bag down his throat.

According to MCSO officials, Ward said he had no regrets for the attack.

Ward has been charged with first-degree murder for Walker's death.

Walker had been in custody since Nov. 27 for armed robbery and kidnapping.

Ward has been in custody since March 12 after allegedly killing Austin Tapia in their Phoenix home. The boy was found with multiple stab wounds. After his arrest, Ward reportedly told police that he "just felt like killing."

Ward pleaded not guilty to charges of first-degree murder, child abuse and aggravated assault.

MCSO officials said Ward had been in jail on 11 different occasions since 2006 with no major disciplinary problems or notable institutional history.
