Greenshields was last seen in Tampa, Florida on October 31, 1989. He celebrated Guavaween, Tampa's Halloween festival, dressed as the Batman character the Joker. He apparently returned to his apartment afterward. He has never been heard from again. He left almost all his belongings, including his Joker costume, clothes, shoes, car keys, gold jewelry and late model Jeep Cherokee, behind at his home; only his wallet was missing.
Greenshields served three years in the Army after his graduation from Chamberlain High School. In 1987, he was sentenced to three years' probation for illegal possession of the drug Valium. Greenshields paid all his fines and kept in contact with his probation officer as required. In January 1990, police isused a warrant for his arrest for probation violation. His probation was almost over by the time he disappeared, and his probation officer stated he didn't fit the profile of someone fleeing from the law.
Greenshields's driver's license expired in 1992, and he never renewed it. The circumstances of his disappearance are unclear.
