An arraignment was held on Sept. 18 for Cecil D. Walker, who allegedly beat and stabbed his 86-year-old mother to death on Aug. 27, 2010 in Black Diamond.

The defendant entered a not guilty plea to the charge of first-degree murder with a deadly weapon. King County Prosecutors refiled the charge against Walker on Sept. 4. For the past four years, Walker, 54, has either been confined at the King County Jail or a patient at Western State Hospital. He was found incompetent in January 2012 and civilly committed at Western State Hospital. Last month, Western State notified prosecutors of the hospital’s intent to petition the court to modify the current commitment order to allow for less restrictive placement in the community.

Walker was booked into the King County Jail prior to his release into the community. A case setting hearing is set for Oct. 2 at the King County Courthouse.
