John Hatzopoulas was 20 when he left his sister’s Worcester, Massachusetts, home about 4:30 p.m. on November 1, 1990, and never arrived for his scheduled work shift. He has not been seen or heard from since.

At the time he vanished John was described as a Caucasian male about 6 feet 0 inches to 6 feet 1 inch tall, weighing roughly 180 to 185 pounds, with brown hair. The Worcester Police Department lists his case among unresolved missing-persons investigations; authorities have not released any major leads.

There has been little public information about his movements after he left his sister’s house, and the case remains open. Does anyone have recollections from Worcester in 1990 or information that could help explain what happened to John?
