A Paso Robles woman accused of killing her mother has been ruled mentally incompetent to stand trial and has been committed to a state hospital for treatment.

San Luis Obispo Superior Court Judge John Trice today found that Sunni Daun Jackson, 36, was too psychotic and combative to be brought into court, and sent her to Patton State Hospital, a psychiatric facility in San Bernardino, for treatment, said James Maguire, the public defender assigned to the case.

This means that the case against Jackson is suspended until she is determined to be competent to stand trial. Late last month, Jackson was so disruptive she could not appear in court for her arraignment.

Jackson is accused of killing her mother, Earlene Louise Grove, 61, in a one-bedroom granny unit on Olive Street in Paso Robles on April 20. Grove died from multiple stab wounds to the upper torso, with a contributing factor of blunt-force trauma to the head, according to preliminary autopsy results received by the Paso Robles Police Department.

The suspect has a long criminal record and had contacts with Paso Robles police for bizarre behavior going back to 1991.

The staff at Patton State Hospital will be given the duty of helping her regain competency so she can understand the case against her. Only then can court proceedings resume. If she remains incompetent, she will stay at Patton.
