23 year old Robert J Kopejtka of Rock Port was seriously injured Tuesday afternoon after crashing his vehicle on Route A, just east of Watson in Atchison County. Kopejtka was northbound on Route D, when he had brake failure and came to the intersections of Route D and A. He crossed Route A and began to skid striking an anhydrous ammonia tank on private property. Kopejtka became pinned in the cab after the tank tipped over onto its side. Kopejtka was airlifted to University Hospital in Omaha.
