Christopher Lawrence Duffy, 16, disappeared from his Spanaway, Washington, neighborhood after leaving his home on 168th Street East about 9:00 p.m. on March 20, 1985. He told his mother he was going to help a friend with car trouble and drove off in the family’s 1979 Pontiac Firebird, promising to return within the hour. When he didn’t come back his family reported him missing; five days later the Firebird was found burned out near the Fort Lewis Reservation.

Investigators established Christopher had picked up two acquaintances that night: 16-year-old Eugene Gene Quillin and 20-year-old James Jim Allan Dunlap. The three went to the Nisqually River, where an altercation occurred. Quillin allegedly threw Christopher to the ground and killed him. Quillin and Dunlap then disposed of his body by throwing it from a bridge into the Nisqually River; Christopher’s remains have never been recovered. Quillin was later tried as an adult and convicted of first-degree murder, possession of stolen property, and malicious mischief, and Dunlap pleaded guilty to second-degree murder and received a 12-year sentence.

Does anyone have information about Christopher’s movements that night or about the Firebird’s location before it was found burned near Fort Lewis?
