VANCOUVER, Wash. (KOIN) — The 50-year-old woman accused of killing her elderly mother allegedly started to dig a grave after she beat her until she stopped moving.

The probable cause of Asekna Miller-Wilber’s arrest was revealed during her court appearance on Monday. She was arrested Sunday for the death of her 75-year-old mom and charged with 2nd-degree murder.

Carole Hardin was found dead Thursday night after Miller-Wilber went to a neighbor’s home to call 911, however, it’s believed Hardin died sometime on Wednesday, possibly earlier. Wilber had been living with her mother at their home on 14308 NE 80th St. in the Orchards area of Vancouver.

Deputies said, upon arrival, that Hardin had “apparent” injuries to her face and head as well as her wrist. 

According to the probable cause, Miller-Wilber’s mother physically hit and abused her for “her entire life.” She told officers they would get in arguments sometimes. Prior to Thursday, Miller-Wilber and Hardin got into argument that led to a physical fight. The probable cause states that Wilber had to remove a pair of scissors from her mother during the struggle.

The fight allegedly started in the living room and ended in Hardin’s bedroom where Miller-Wilber repeatedly punched her mother in the head until she stopped moving. Then, Miller-Wilber became confused and instead of calling 911, she allegedly started to dig a grave in the backyard for Hardin. The probable cause says she continued digging for an entire day until she became too tired.

Responding officers later said they found a hole in the backyard that was several feet deep. 

The probable cause also shows that Miller-Wilber had pictures on her camera that were taken over 24 hours before she went to her neighbor’s home. Officers said the pictures show the home and Miller-Wilber’s injuries to her hands and arms that are reportedly from her fight with Hardin.

During her court appearance Monday, Miller-Wilber immediately requested death by lethal injection — saying, “The court doesn’t want me alive and neither do I.”

Wilber’s attorney argued that Hardin may have been the aggressor in the incident and added that Miller-Wilber was afraid of her. 

According to the state of Washington, this isn’t Miller-Wilber’s first run-in with the law. She has a criminal history dating back to 2013. She’s been convicted of three counts of 2nd-degree assault and felony harassment. 

In addition, the state said Hardin asked for a domestic violence protection order on May 17, 2018 protecting herself from Miller-Wilber. A temporary protection order was issued on May 29, however, it was dismissed on June 5 when neither Hardin or Miller-Wilber showed up to court.

Miller-Wilber’s bail was set at $500,000 and her next court appearance is scheduled for Oct. 12. She’s on watch for suicide.
