Authorities say alcohol may have contributed to a weekend accident that seriously injured four area men.

According to the highway patrol report, Toby Kenyion, 23, of Jay, was driving south on Oklahoma Highway 28 at approximately 7:45 p.m., Saturday, when he apparently crossed the center line and struck a northbound GMC truck head-on.

Kenyion was pinned in his 1990 Pontiac for approximately 15 minutes before being airlifted to a Joplin hospital, where he is listed in critical condition.

The driver of the truck, Jeremy Matthews, 29, of Langley, and two passengers, Lawrance Panther, 51, and Fredrick Sharp, 43, were pinned in the truck for up to 20 minutes. They were airlifted to three separate area hospitals and are all listed in serious condition.

Trooper Eric Gibe said seatbelts were not in use by any of the accident victims. Authorities believe Kenyion was intoxicated at the time of the accident.
