Funeral services for the four people who died Saturday in a Grady County head-on collision will be held today and later this week.
A service for Heather Nicole Doughty, 17, of Chickasha has been scheduled for 2 p.m. Saturday at Bible Baptist Church in Chickasha.
Doughty was the driver of a car that struck a vehicle driven by Delbert H. Tolle, 69, of Waukomis on U.S. 81 north of Chickasha. Tolle was also killed.
Tolle's funeral is set for 2 p.m. Friday at Ladusau-Evans Funeral Home chapel in Enid.
Passengers in Doughty's car who also were killed were Kalynn Brooke Pena, 14, and Sara Savana Lane, 15, both of Chickasha.
A funeral service for Pena is scheduled for 2:30 p.m. today and a service for Lane is set for 2:30 p.m. Friday at Bible Baptist Church in Chickasha.
An Oklahoma Highway Patrol spokesman said today that troopers do not know why Doughty swerved left of center and struck the car driven by Tolle.
