Spilotro and his brother Michael disappeared on June 14, 1986, after they drove away together from Michael's Oak Park home. Michael's wife, Anne, reported both brothers missing on June 16. Michael's car, a 1986 Lincoln, was recovered several days later in a motel parking lot near O'Hare International Airport. On June 22, their bodies were found, one on top of the other and stripped down to their undershorts, buried in a cornfield in the Willow Slough preserve near Enos, Indiana. The freshly turned earth had been noticed by a farmer who thought that the remains of a deer killed out of season had been buried there by a poacher, and notified authorities. An autopsy completed on June 24 identified their cause of death as blunt force trauma, and ascertained that they had been dead since June 14. They were identified by dental charts supplied by their dentist brother, Patrick Spilotro. The two were buried in a family plot at Queen of Heaven Cemetery in Hillside, Illinois, on June 27.
