An SUV veered across a highway median in the Oklahoma Panhandle early Wednesday and slammed head-on into an oncoming van full of men headed to work at a Texas meatpacking plant, killing both drivers and five of the six van passengers, authorities say.

The Chevy Suburban was moving fast and passed a couple of trucks on Highway 412 just before it crossed the center line and collided with the van near Elmwood, Oklahoma, according to  Highway Patrol Trooper Betsy Randolph.

All seven of the men in the van were from Liberal and Dodge City.   They were headed to work at Booker Packing Company in Booker, Texas.

Randolph says the SUV driver was from Woodward, Oklahoma.  The surviving van passenger was airlifted a hospital in Amarillo, Texas.
