Vahik Avanas, 56, was last seen December 6, 2014, near the Romero Visitor Center on California Highway 152, about 14 miles west of Los Banos, California.

He was wearing dark blue jeans, a T-shirt and black sports shoes when last seen. Extensive searches reportedly produced no trace and his case is classified as endangered missing.

Anyone who was in the Romero Visitor Center area on December 6, 2014, or who has information about Avanas’ whereabouts is asked to contact the Los Banos Police Department.
