One person was sent to the hospital following a single-vehicle accident Saturday evening south of Elk Horn, in Shelby County. The Iowa State Patrol says 56-year old Janet Snyder, of Elk Horn, was transported to the Cass County Memorial Hospital in Atlantic by Elk Horn Rescue, following the accident which happened at around 5:15-p.m on Highway 173, just north of Interstate 80. The Patrol says according to witnesses, Snyder’s 2002 Ford Explorer left the road slowly just past a residence at 146 State Highway 173 and continued well into a corn field before coming to rest. Officials say it appears the accident occurred when Snyder suffered from some sort of medical condition.
