Woman pleads guilty to killing her 2-year-old son

TACOMA -- A woman who called 911 last year and confessed to killing her 2-year-old child formally pleaded guilty to second-degree murder Wednesday.

Aleesha Walker, 28, will be sentenced in Pierce County Superior Court on Sept. 6.

On March 30, 2012, Walker called 911 about 7 a.m. and told the operator she had just "murdered her child," court documents stated.

She told the operator she struck the child's head on a dresser and made a comment about smothering him. She also said that she was reacting to voices she was hearing.

When officers arrived on the scene, they saw the toddler, naked on the floor with dried blood spots on his face.

"God know what I did," Walker allegedly told officers at the scene. "I'm bad for doing what I did, I did it to my baby. He's gone."

Officers noticed that Walker had dried blood on her hands and knees. A downstairs neighbor also told police that he awoke to the sound of a thud on the floor about 6 a.m. on March 30.

The child was transported to Mary Bridge Children's Hospital and was pronounced dead shortly after arrival.

A Pierce County medical examiner said the autopsy showed that the boy had suffered head injuries, but that they were not fatal and the likely cause of death was smothering.

An investigation showed that there had been a number of referrals to Child Protective Services in regard to Walker and her son.

Sherry Hill with CPS said that the last time the agency had contact with Walker was in June 2011 for suspicion of drug use, poor hygiene and domestic violence with the boy's father. Hill said the allegations were unfounded.
