In the late summer of 1984, Terry Lynn Sovey, a 25-year-old single mother from Pontiac, Michigan, traveled to the small village of Millington. She was accompanied by a man named William Bibby. The two were reportedly involved in several thefts in the Millington area during their time there. Terry was last seen on September 22, 1984, and has not been heard from since. Her disappearance left her loved ones searching for answers that have remained elusive for decades.
The only account of Terry's last known moments comes from William Bibby. He told investigators that he and Terry had driven to a rural, undeveloped, and swampy area behind a farmhouse. According to Bibby, they had an argument, after which Terry met someone else in the vicinity and decided to stay with them. He claimed to have lost his car keys and left the area on foot, leaving his vehicle behind. Law enforcement conducted searches of the swampy area, even bringing in canine units, but found no evidence connected to Terry's disappearance. The investigation was further complicated by the refusal of potential witnesses to cooperate with authorities, reportedly out of fear of getting into trouble for not coming forward sooner.
Following Terry's disappearance, William Bibby was incarcerated for the thefts he committed in Millington. After being paroled to Troy, Michigan in 1993, he vanished sometime between September and November of that year. His whereabouts remain unknown to both his family and the police, and he is now considered a missing person with a warrant for a parole violation. The Oakland County Sheriff's Office continues to investigate Terry's case and has expressed a desire to locate and re-interview Bibby, should he still be alive. The circumstances surrounding Terry Lynn Sovey's disappearance remain unclear, and her case is an unsolved and ongoing investigation.
Terry Lynn Sovey was a 25-year-old female who was last seen on September 22, 1984, in Millington, Michigan. She was from Pontiac, Michigan, and public records also identify her by the name Terry Gayton. The Charley Project lists her as an endangered missing person and describes her as a white woman with blonde hair and hazel eyes, standing about 5 feet 1 inch to 5 feet 2 inches tall and weighing approximately 120 to 130 pounds. She had a tattoo on her left shoulder, a distinguishing feature that could help identify her. Her disappearance began in a small village far from her home community, and what is known about the case has remained troubling for decades because the last public account of her whereabouts came from a man who later disappeared himself.
Terry had gone to Millington during the summer of 1984 with William Edward Bibby. According to investigators cited in public reporting, Bibby committed thefts in the Millington area while the two were visiting, and Terry was last known to be in that area with him. Local 4 reported that Terry was a single mother living in Pontiac, and investigators described Millington as a small village with just over 1,000 people. The public record does not describe every step of Terry's movements that summer, but it does place her in Millington with Bibby before her disappearance, and it indicates that their time there became part of a broader investigation involving thefts, reluctant witnesses, and unanswered questions.
Bibby later told investigators that he and Terry had gone to a rural area near Millington and parked behind a farmhouse in an undeveloped, swampy area. According to the account attributed to him in The Charley Project and Local 4 reporting, the two argued, and Bibby claimed that Terry met someone nearby and stayed there. He said he lost his keys and left on foot, leaving the car behind at the farmhouse. That statement became the last known narrative connected to Terry's disappearance, but it did not lead to Terry being found. Authorities searched the swampy area with dogs, but no evidence explaining what happened to her was located. Potential witnesses were reportedly tracked down but were unwilling to cooperate, with officials saying some were afraid because they had not helped earlier in the investigation.
After Terry vanished, Bibby served time in prison for the thefts committed in Millington. He was paroled to Troy, Michigan, in 1993, but then he also disappeared sometime between September and November of that year. The Charley Project states that Bibby is listed as a missing person and has an outstanding warrant for parole violation. He has not been named as a suspect in Terry's case, but investigators have said they would like to locate him, if he is still alive, so they can re-interview him about what happened to Terry. His disappearance left investigators without the last known person who could potentially answer key questions about the rural area, the argument he described, the unidentified person he claimed Terry met, and the events surrounding the car left behind.
The available online sources do not state that Terry Lynn Sovey has been found alive or deceased, and they do not provide a public resolution status. They also do not provide a confirmed explanation for who last saw her after Bibby's account, whether the person he described existed, or what happened after she was last known to be in the Millington area. What can be said with care is that Terry Lynn Sovey, also known as Terry Gayton, was a 25-year-old female from Pontiac who disappeared from Millington, Michigan, on September 22, 1984; she had traveled there with William Bibby, was last associated with a rural swampy area near a farmhouse according to Bibby's account, and was never heard from again. The overview of the case is that a young mother vanished in a small Michigan village under unclear circumstances, the last person known to have seen her later disappeared himself, searches and investigative efforts did not resolve what happened, and the case remains a decades-old mystery shaped by silence, fear, unanswered questions, and the continuing need for credible information.
