GRAYSON COUNTY, TX -- A woman is dead after authorities say her car veered off a boat ramp and drove into Lake Texoma.
Around 5:35 P.M., Denison officials say they got the call that a car had driven into Lake Texoma.
By the time they got to the scene, the car had sunk under the water completely.
Denison Assistant Fire Chief, Bill Ray, says bystanders saw the car veer off the boat ramp, hit the rocks, then sink into the water.
He says when first responders arrived on scene, the car was not visible.
A short time later, divers found the car, 25 feet underwater.
When they pulled the car out of the lake, Ray says someone was inside.
"Once the divers came down the car was inverted there was a lot of silt and mud they couldn't see inside the car, so we opted to pull the vehicle out inside was one female approximately age 50 years old," Ray said.
The woman has not yet been identified, and Ray says they're not sure what caused the driver to veer off the road.
The Grayson County Sheriff's Department is investigating the case.
