A Huntington Beach man pleaded not guilty Friday in the fatal stabbing of a co-worker at Cal State Fullerton.

Online court records show that Chuyen Vo pleaded not guilty to one count of murder in the death of Steven Chan, 57, who was stabbed in a university parking lot Aug. 19.

Vo is due back in court Nov. 22. His attorney, Ed Welbourn, had no comment.

Chan retired from an administrative job at the college in 2017 but returned this year to work as a consultant.

Police declined to discuss the relationship between the co-workers.
