William Edward Bibby was 38 when he vanished from Troy, Michigan, sometime between September and November 1993 after being paroled earlier that year to a residence in Oakland County. After his release he made one recorded phone call to his brother and then had no further contact with family. A parole warrant for violation remained outstanding and the Michigan Department of Corrections listed him as an absconder from parole as of December 7, 1993.

Bibby is described as a white male with brown hair and hazel eyes, standing between 5 feet 7 inches and 5 feet 9 inches and weighing 170 to 190 pounds. Distinguishing marks include a scar on his back, a scar on his right wrist, and a tattoo of the number 13 on his right forearm.

His disappearance is linked to an earlier unresolved case. In 1984 Terry Sovey, 25, went missing from Millington, Michigan; Bibby was the last known person to have seen her. He told investigators they had argued in a rural, swampy area behind a farmhouse, that she met someone else there, and that he left on foot after losing his car keys. He later served prison time for thefts committed in the area. Law enforcement has expressed a desire to re-interview him about Terry Sovey’s vanishing.

The Oakland County Sheriff’s Office maintains the file on Bibby’s disappearance. Does anyone have information about his movements in late 1993 or about contacts he may have had after that phone call to his brother?
