Michael Willis Costlow was 32 and living in Phoenix, Arizona when he was last seen at his residence at 1445 1/2 East Garfield Street in August 1981. The exact date of last contact is not known. Public details about his life, work, and relationships are scarce.

Michael was a white male with light brown hair, blue eyes, and prescription glasses. A notable physical feature was a missing right index finger. On September 30, 1981 his car — a blue 1971 Dodge Colt with Arizona plate TXB155 — was found locked and unoccupied in the remote Lake Mead area. No sign of Michael has been reported since the vehicle was recovered.

The Phoenix Police Department handles the investigation, but little public information about leads or theories has been released. Does anyone have information about Michael’s last known movements in Phoenix or who might have seen him around August 1981?
