A Guymon man has been killed in a single-vehicle crash in the Oklahoma Panhandle.
 
     The Oklahoma Highway Patrol says 29-year-old Richard Joseph Vickroy died early Friday after the vehicle he was driving went off a Texas County road southeast of Guymon.
 
     An OHP report says Vickroy was northbound when he apparently swerved and his vehicle went off the roadway and rolled.
 
     The report says Vickroy wasn't wearing a seatbelt and was thrown from the vehicle.
