Ronald Pritchett, accused of stabbing his parents during an argument about dinner and killing his father, has been found mentally incompetent to stand trial.

Pritchett was declared unfit after a brief hearing in 24th Judicial District Court in Gretna on Wednesday, but wasn’t formally charged with the crime until he was indicted by a grand jury Thursday for second-degree murder, attempted second-degree murder and unauthorized use of a vehicle.

Judge Donald Rowan on Wednesday ordered Pritchett sent to East Louisiana State Hospital in Jackson after a psychiatric evaluation found him incapable of understanding the charges against him and assisting in his own defense. He will remain there until the day the hospital staff finds otherwise, according to court documents.

Pritchett, 32, was arrested in Mississippi on November 40, four days after allegedly stabbing his mother, Renita, and father, Percival, who died from his wounds at their home in the 800 block of Bellemeade Boulevard just outside Gretna.

Pritchett was upset after finding out his parents bought dinner at McDonalds but hadn’t brought anything back for him.

Pritchett was examined last month by Dr. Raphael Salcedo and Pritchett’s mother, Renita, told prosecutors and Pritchett’s attorney with the Public Defender’s Office that her son has struggled with mental health problems for years.
