John Duane was 36 when he was last seen in Brooklyn, New York, on February 3, 1989. He was driving a 1980 Buick with license plate TCU315; both he and the vehicle have not been located. Authorities have noted he may have jumped from the Williamsburg Bridge, a detail that has remained part of the case narrative.

John is described as a white male, 5 feet 10 inches tall, about 150 pounds, with brown hair and brown eyes. The New York City Police Department Missing Persons Squad handled the investigation, and the case remains open with few public updates or significant leads. The lack of witnesses or additional evidence has left the circumstances of his last known day incomplete.

If anyone saw John, his Buick TCU315, or has information about that February day in 1989, please share what is known.
