There are new developments in the investigation into the remains of six people found submerged in two cars, dating back to the 1950s and 1960s.
They were pulled from Foss Lake, about 75 miles northeast of Altus, last September after being discovered during an OHP sonar training exercise.
One car was a '52 Chevy and the other was a '69 Camaro. Both contained the remains of three people.
According to Oklahoma City news reports, the state medical examiner's office positively identified one set of remains found in the Chevy as those of Clebern Hammack. The autopsy reports shows Hammack was not injured at the time of death and ruled her cause as probable drowning.
Another set of remains found in the Camaro have also been identified as those of 16-year-old Jimmy Williams. The report shows Williams was not injured at the time of death as well. His cause of death was also determined to be a drowning.
Authorities believe both deaths were accidental.
An Elk City man, and a male and female friend were last seen in the '52 Chevy around 1969. The next year three teens from Syre, Oklahoma were supposed to be taking the '69 Camaro to a football game in nearby Elk City, but never made it and were never seen again.
Investigators are still working to positively identify the other four people.
