An Atascadero woman accused of killing her mother in Paso Robles in April has schizophrenia and has suffered from mental illness since 1996, according to a search warrant.
Sunni Daun Jackson, 36, is accused of killing her mother, Earlene Louis Grove, 61, in a one-bedroom granny unit on Olive Street in Paso Robles on April 20.
She was found mentally incompetent to stand trial and is currently receiving treatment at Patton State Hospital, a psychiatric facility in San Bernardino.
Jackson has suffered from mental illness since 1996, according to a relative whose name is redacted in the document, and she was taking medication for schizophrenia.
When Jackson does not take her medication and she often does not, Jackson can become violent, the warrant states.
Jackson had a previous assault against her mother that resulted in serious injury, and shed spent time in Patton for that incident, Paso Robles Police Department officials said in the warrant.
A status report regarding Jacksons mental health competency is scheduled for Aug. 9 before San Luis Obispo Superior Court Judge John Trice.
Paso Robles police spoke with Jacksons roommate, who said she didnt believe Jackson was taking her medication around the time of Groves killing. Police were looking into her medication supply to try to verify that information.
They also were searching for any illegal drugs, bloody clothing and possible weapons used in the attack.
Investigators found a cobblestone and knives that might have been involved in the attack. Grove suffered blunt-force trauma to her head and multiple stab wounds.
Some mental health advocates have cited Jacksons case as an example of one that should encourage San Luis Obispo County leaders to enact Lauras Law, which would allow for required outpatient treatment of those who commit repeat criminal offenses or have been hospitalized repeatedly after refusing to comply with treatment.
But county officials have held off implementing the legislation, saying that its too costly in a struggling economy and that forced treatment of patients isnt effective.
