Rogers County prosecutors charged a Collinsville man in connection with a fatal September 12 crash on Highway 88 at the Oologah Lake Dam.
The Oklahoma Highway Patrol said Eric Coager, 34, was driving west when his car went off the highway and rolled, killing two passengers.
Prosecutors charged Coager Wednesday two counts of first-degree manslaughter and one count of DUI-great bodily injury.
He was arrested four days after the crash when he was released from a Tulsa hospital.
The OHP says Angela Brown, 32, and 11-year-old Aden Williams died in the crash. Troopers said Coager was driving his 1991 Pontiac Firebird Trans Am at an unsafe speed when he failed to negotiate a curve on the south end of the dam.
A third passenger, a six-year-old boy, was injured in the crash but survived.
