A report was released Friday from the State Medical Examiner’s Office with regard to a fatal airplane crash that took place Nov. 9th. Officials said all four victims of the crash died from “multiple blunt force injuries in the setting of carbon monoxide toxicity.”

A distress call from a person on the plane said those on-board thought the pilot, 49-year old Edward Ralph Anderson, of LeMars, had suffered from a heart attack. A student pilot on the plane attempted a landing at the Guthrie County airport near Guthrie Center, but the plane dropped off radar. The wreckage wasn’t found until around 6:30-the next morning, in a cow pasture southwest of Guthrie Center.

In addition to the pilot, 36-year old Patrick Kellen, and 15-year old Samantha Clark, both from Le Mars, along with 28-year old Tyler Douvia, of Merrill, died in the crash. The accident remains under investigation by the National Transportation Safety Board (NTSB).
