Three people were killed early Saturday morning when a semi-truck crossed a median on Interstate 40 near Vian and struck the vehicle in which the three were occupants.

The Oklahoma Highway Patrol (OHP) reported that the accident occurred at about 12:18 a.m. Saturday.

The OHP reported that James Crozier, 35, of Byromville, Ga., was driving a 1987 Peterbilt truck west on Interstate 40 when his truck went across the median, striking a 2006 Toyota Corolla driven by Norman Winkley of El Paso, Texas.

After striking Winkley's vehicle, Crozier's semi-truck then struck a bridge pillar, according to the OHP.

Crozier was taken by helicopter to St. Edward Mercy Medical Center in Fort Smith, Ark., where he was listed in stable condition with a leg injury, the OHP reported. He was reportedly later transferred to another Little Rock, Ark., hospital.

Winkley, 63, who was thrown from the vehicle, was pronounced dead at the scene with internal and external injuries. Two passengers in Winkley's vehicle were also killed. The OHP reported that Kwinnelle Smith, 77, of Las Cruces, N.M., was pronounced dead at the scene with a head injury, and Premadonna Delaney, 61, of Odessa, Texas, was pronounced dead at the scene with internal, leg, and head injuries. Delaney was also thrown from the vehicle, the OHP reported.

The three victims were reportedly on their way to funeral in Arkansas.

According to the OHP, Crozier was "sleepy," and the cause of the collision was listed as inattentive driving.
