For more than a generation, a rural community in the US has been haunted by a mystery: what happened to three teenagers who headed off to a high school football game in the early 1970s and were never seen again?
Police believe they may finally have an answer after divers on a training exercise using new sonar equipment discovered a car containing skeletal remains in a murky lake. Divers also recovered a second vehicle containing bones, and investigators were searching on Wednesday for other cold cases that might match the grim discovery.
Bodies recovered from Oklahoma lake
Six bodies, believed to have been missing for decades, are found after two vehicles are recovered from a lake in Oklahoma.
The cars were found not far from a marina but Custer County sheriff Bruce Peoples said it was no surprise that the murky waters held a secret.
"This lake isn't crystal clear. It's a typical western Oklahoma lake with a lot of silt in it. The visibility is only six to 12 inches on a good day," Sheriff Peoples said. "We'll consider it a mystery until we prove otherwise."
The sheriff said it was entirely possible that people simply drove into Foss Lake and drowned.
"We know that to happen, even if you know your way around. It can happen that quick," he added.
The sheriff said he was confident the dive teams had found the teenagers because one of the cars was a Chevrolet Camaro that appeared to match the description of the vehicle the two boys and one girl were in when they vanished in 1970. The other vehicle found was a Chevrolet from the early 1950s.
"We thought it was just going to be stolen vehicles, and that's not what it turned out to be, obviously," Highway Patrol spokeswoman Betsy Randolph said.
The origins of the second vehicle were less clear. It was found 15 metres from the end of a boat ramp.
Tim Porter of Enid said he believed the remains could be those of his grandfather, John Albert Porter, who disappeared along with two other people in 1969.
"Forty-something years of wondering who or why," Mr Porter said. "If it is my grandfather in there, it's a gift."
The sheriff said on Wednesday he was not sure whether the cars held five or six bodies. The state medical examiner's office believed the remains of six people were recovered.
The bones were being sent to the medical examiner's office for identification and to determine the cause of death.
Divers had found three skulls as of Tuesday evening. They planned to continue looking for more remains, Ms Randolph said.
Authorities hoped the discoveries would offer some relief to families who may have gone decades wondering about the fate of missing loved ones.
"We're hoping these individuals, that this is going to bring some sort of closure to some families out there who have been waiting to hear about missing people," Ms Randolph said. "If that's the case, then we're thrilled."
