A 67-year-old Wyoming man is dead following a single-vehicle rollover near Arlington Friday evening.

The Wyoming Highway Patrol says Robert Kofford was headed east on Interstate 80 around 6:45 p.m., when he lost control of his pickup and rolled it.

Kofford and his passenger, Mrs. Evans, were not wearing their seat belts and were thrown from the pickup.  Kofford died on scene.  Evans was taken to Ivinson Memorial Hospital in Laramie and then flown to Denver.

The Patrol says it was snowing and road conditions were slick at the time of the crash.  Speed and a possible medical condition are being investigated as contributing factors.
