PHOENIX - A man accused of killing his 12-year-old half-brother is now accused of killing his cellmate at the Lower Buckeye Jail in Phoenix.
According to the Maricopa County Sheriff’s Office, Andrew Ward was arrested Thursday after allegedly attacking his cellmate, Douglas Walker.
MCSO said inmates on Wednesday night notified officers that a fight had occurred inside a locked cell around 7:30 p.m.
When officers arrived at the cell, they found Walker on the floor bleeding.
MCSO said Walker had been beaten, stabbed with a golf pencil and had peanut butter smeared over his head. Paramedics told MCSO Walker's breathing was obstructed by a plastic bag around his nose and throat.
Ward, 27, was removed from the area and subsequently admitted to officials that he choked and beat Walker.
Ward told officers that he first tried to cut Walker's throat with a plastic playing card, then used a pencil to stab his cellmate's eyes and throat. The attack ended after Ward stuffed a plastic bag down Walker's throat.
Ward told MCSO he had "no regrets" about the attack.
Ward is now being charged with first-degree murder for the death of Walker.
Walker and Ward were housed together for the past three weeks.
According to court records, Walker was awaiting an April 11 sentencing after he pleaded guilty last month to armed robbery. He had been in custody since November, the sheriff's office said.
Officials said when Ward was arrested on March 12, he was put in an isolation cell during intake because he was a high-profile criminal.
While he was going through intake and before he was transferred to Lower Buckeye Jail, he made a suicidal comment. Because of the comment, he underwent a 24-hour medical evaluation, according to MCSO.
The medical team cleared him, and he returned to a cell shared with Walker on March 14, MCSO says.
MCSO says it didn't suspect he was violent -- he had been booked 11 times since 2006 and didn't have a booking history of violence.
Police said the boy's mother and sisters were at dinner when the incident occurred and arrived home to find police on scene.
Detectives interviewed Ward about the crime.
When asked why he killed his brother, he reportedly said, “Honestly, I just felt like killing."
Police told ABC15 Ward called 911 from a nearby convenience store to report the crime.
