44 YEARS MISSING: Sonar Testing Found Their Chevrolet Beside Another Car in Foss Lake

In September 2013, Oklahoma Highway Patrol troopers training with new side-scan sonar at Foss Lake found two cars on the bottom, three feet apart, near the main boat ramp. Inside were six people missing since 1969 and 1970. This documentary follows both disappearances: three adults from Canute and Sayre who vanished in April 1969, and three Sayre teenagers who never arrived at a football game in November 1970. It covers the decades of rumors, the technology that finally saw through the murky water, the 13-month DNA identification process, and what the medical examiner could and could not establish. True Crime Files documents real investigations, cold cases, missing-person cases, forensic breakthroughs, search-and-recovery operations, and the evidence that changes how old cases are understood. Some visuals are illustrative reconstructions created to support the documented timeline. They are not original footage of the events.
