Three Craig residents were killed Friday morning when the tractor-trailer they were traveling in veered off an overpass in Oklahoma.

The truck was traveling northbound on U.S. Highway 75 outside of Ramona,Okla., when the truck first crossed the center line of a Highway 75 overpass, and then veered off the overpass, falling 30 feet to the railroad tracks below.

According to an Oklahoma Highway Patrol report, the truck’s driver, Wade Kancilia, 22, apparently fell asleep at approximately 6:30 a.m. Friday while driving.

Kancilia’s two passengers, Wendy Marie Graham, 21, and her 21-month-old son, Ryan Paul Empson-Graham, were also killed.

Graham had left Craig on March 10 to visit family in Kansas and Kancilia in Dallas, said her roommate, Rose Sperry, 17. Sperry was traveling in the caravan returning to Craig that included Sperry’s vehicle, Kancilia’s truck and a second tractor-trailer when the accident occurred.

Sperry, who attended classes with Graham at Colorado Northwestern Community College, said she was “devastated” by the losses of Graham and her son.

“Wendy was a great person with a big heart who cared a lot for her friends and family,” said John Collier, a friend of Graham’s. “Her heart and house were always open, and she was a good mother to her son. She’ll always be in my heart, no matter what.”

The loss of Graham and her son isn’t something longtime friend Steven Baptist can really grasp yet.

“I haven’t totally processed it yet,” Baptist said. “When I wake up, I still expect her to be at her trailer, with Ryan running around trying to wake everyone up.”

Ironically, the child’s father, Ryan Empson, was also killed in a tractor-trailer crash. He was killed in October 1999 in an accident on Nine Mile Pass outside of Meeker.

The funeral for Wendy Graham and Ryan Paul Empson-Graham will be held Tuesday at 2 p.m. at the First Christian Church in Craig.
