(TWIN FALLS, ID) – 21 cows were killed Tuesday when a semi truck hauling them overturned south of Twin Falls Tuesday. Forty-eight-year-old Kenneth Womack was reportedly driving on a rural road when he missed a curve and rolled the semi and trailer. Crews had to cut into the trailer to get the cows out, 34 of which survived the crash. Womack, who suffered minor injuries, was cited for driving too fast for conditions. The accident blocked the road for about four hours.
