Naugle’s arraignment in Placer Superior Court was scheduled for Friday.
Television news cameras captured a man wearing a long, dark apron, believed to be Naugle, being taken into custody by Placer County sheriff’s deputies.
Sheriff’s officials and Thunder Valley representatives said the attack occurred in a kitchen area that served Dos Coyotes and was separated from the restaurant and casino floor. Casino operations continued normally during the incident, Thunder Valley representatives said, and many guests on the sprawling property were likely unaware of the attack.
