Green was last seen at the New Temple Mount Zion Christ Church in the 1600 block of Nostrand Avenue in the New York City borough of Brooklyn on December 15, 1985. He disappeared in the company of his non-custodial father, Junior Lee Smith, and his non-custodial paternal grandmother, Merline Wright. Smith's date of birth is July 4, 1966; he was nineteen years old at the time of his son's disappearance. He and Wright were later located without Green, and Smith admitted to disposing of Green's body.

Smith was never charged in connection with his son's case. He was later incarcerated twice for burglary and robbery. The child's remains have never been located, but foul play is suspected in his disappearance.
