A Baton Rouge woman accused of manslaughter in the 2014 death of her 82-year-old mother, who was found naked in a wheelchair in feces and riddled with infected bedsores, was sane at the time, a state judge ruled Thursday.

District Judge Mike Erwin made the finding after receiving reports from a psychologist and a neuropsychiatrist who examined Joleslie Looney, 55, and agreed she was sane at the time of Bessie Looney's death on Sept. 29, 2014.

In July, the judge found Looney competent to stand trial. Her 19-year-old daughter, Lauren Looney, also is charged with manslaughter in the case.

Erwin decided in May that Lauren Looney, who was 17 when her grandmother died, was sane at the time and is competent to stand trial.

Joleslie Looney's court-appointed attorney, Stephen Sterling, said he disagrees with the doctors' findings regarding his client.

Joleslie and Lauren Looney were Bessie Looney's primary caregivers, authorities have said.  

She died in their North Acadian West home. Coroner Beau Clark ruled her death a homicide after an autopsy showed she died from a blood infection caused by infected bedsores. He also said malnutrition, dementia and heart disease were contributing factors in her death.

The elderly woman was found sitting atop a soiled disposable pad that investigators suspect had been there for a while. She also was surrounded by trash, gnats and fruit flies, according to police.

The Looneys told police they were aware of her condition but it "did not appear to be severe to them," according to an affidavit of probable cause.

Joleslie Looney appeared in Erwin's courtroom Thursday in green East Baton Rouge Parish Prison clothes. Lauren Looney is free on bail.

Prosecutors intend to try the mother and daughter separately. They each face up to 40 years in prison if convicted of manslaughter.

Joleslie Looney's next court date is March 6. She does not have a trial date. Lauren Looney, who turns 20 next week, is due in court Jan. 27 for a status hearing.
