Area Oklahoma Highway Patrol troopers continue investigations into the deaths of two pedestrians who died within hours of each other in separate highway accidents.

Carol Coker, 54, died on state Highway 76 about 5:35 p.m. Wednesday. Patrol reports indicate the Ratliff City woman was walking northbound on the northbound shoulder of the highway when she was struck by a northbound 2000 Buick, driven by 55-year-old Charles Jackson, Fox.

Coker was pronounced dead at the scene one mile south of Ratliff City. Jackson was not injured.

Capt. Ronnie Hampton, commander OHP Troop F, Ardmore, said the investigation continues into the reason Jackson veered off the highway and onto the shoulder of the road seconds before striking and killing the woman.

Troopers, assigned to Troop F, are also investigating the early-morning death Thursday of an unknown man who was apparently lying in the middle of U.S. Highway 377 when he was hit by a pickup 3.2 miles south of Connerville.

Patrol reports said the man was prone in the southbound lane of the highway when he was run over by a southbound 2004 Dodge pickup driven by Douglas Wayne Tyner, 63, Madill. Tyner was not injured. Three passengers identified as Lori Tyner, 50, Madill; Jayson Haskins, 35, Madill; and Heather Cofer, 25, Madill, were riding in the pickup at the time. None of the three were injured.

Late Thursday, troopers were still attempting to identify the victim.
