On September 26, 1981, Charlotte Kinsey and Cinda Pallett, both 13, phoned home to tell their parents that they had been offered work, unloading stuffed animals for a midway arcade at the Oklahoma City fairgrounds. Neither girl came home that evening, and police assigned to track them down discovered witnesses who saw them with an unknown man that afternoon, before they disappeared. The search was still in progress, three days later, when two more girls were reported missing. Sheryl Vaughn, 16, of Newalla, Oklahoma, and Susan Thompson, 16, of McLoud, left home for the fair on September 29, and promptly vanished. Their car was discovered on Interstate 40, east of town, keys still in the ignition, but no trace of the missing girls could be discovered. On October 9, police in Greenville, Alabama, arrested a traveling carnival worker, 36-year-old Donald Michael Corey, on charges of kidnapping Charlotte Kinsey and Cinda Pallett. Returned to Oklahoma on October 13, Corey was cleared of all charges six days later, when police verified that he had been in Texas on September 26. Embarrassed by the error, officers would only say their suspect bore a "striking" facial resemblance to the innocent Corey. At this writing, the four girls remain missing and presumed dead, their theoretical abductor still at large.
