Casino worker pleads not guilty, faces psychiatric review after slashing five coworkers

In Lincoln, California, Joseph Naugle, 22, was arrested after allegedly using a knife to slash five coworkers in the kitchen of the Dos Coyotes restaurant at Thunder Valley Casino Resort. He appeared in Placer County court wearing an orange T-shirt and striped pants, entered a not-guilty plea to multiple attempted murder counts, and requested a psychiatric evaluation to assess his competency for trial. Police responded quickly to a caller’s report, detained Naugle in his apron, and transported one victim to a hospital where he was later released; the remaining four received on-scene treatment.

The evaluation will help determine whether Naugle can stand trial, and he is scheduled to return to court on September 2. Authorities have not disclosed a motive for the incident.
