Alex Ivanisevic Des Moines Register Published 2:01 PM EST Nov 10, 2018 Four people were killed in a plane crash Friday in Guthrie County, according to local law enforcement. Guthrie County Sheriff Marty Arganbright said in a release that a call was received around 5 p.m. Friday from air traffic control in Des Moines requesting an emergency landing for a single-engine aircraft at the airport east of Guthrie Center. Arganbright said the plane left Le Mars in northwest Iowa at 4:15 p.m. and was traveling to Osceola. Traffic control reported that the aircraft dropped off radar approximately four miles southwest of the Guthrie County airport. According to authorities, the pilot, Edward Ralph Anderson, 49, of Le Mars, suffered a heart attack and a student pilot attempted an emergency landing of the plane, which had two additional passengers. Arganbright said a citizen reported seeing a small plane crash in a pasture southwest of the intersection of 265th Street and Maple Avenue at 6:31 a.m. Saturday. “The plane impacted very hard and all occupants were deceased at the scene,” Arganbright noted in the release. Other victims identified Saturday were 36-year-old Patrick Kellen and 15-year-old Samantha Clark, both of Le Mars, and Tyler Douvia, 28, of Merril. The deceased were transported to the Iowa Medical Examiner’s Office and the crash site was secured pending an investigation by the Federal Aviation Administration.
