William Pasquale Riley, known as Billy, was 22 when he vanished from his Evanston, Illinois home on what is believed to have been Sunday, June 17, 1984. He left behind all personal belongings and his vehicle and has had no contact or confirmed sightings since. The disappearance was initially reported to the Evanston Police Department and later handled by the Cook County Sheriff’s Office, but investigators have had few leads and the case went cold.

Billy was described as a white male, 6 feet tall, about 175 pounds, with brown hair and brown eyes. Distinctive features included a small gap between his two front teeth and that he was completely deaf. There is no reliable information about the clothing he was wearing when he left.

The circumstances offer few clues: leaving all possessions and a car could suggest an unplanned departure, but details are scarce and the family remains without answers. If anyone knew Billy, his routines, or saw him around Evanston in June 1984, please share what you remember.
