Federal investigators have reached the site of a South Dakota plane crash that killed nine members of a prominent United States business family on Saturday. Brule County emergency manager Katheryn Benton told the Sioux Falls Argus Leader that the passengers ranged in age from 7 to 81.
The family was returning from an annual pheasant-hunting trip when the plane crashed shortly after takeoff in the midst of a winter storm warning.
The crash also killed Kirk Hansen's children, Stockton and Logan; his sons-in-law, Kyle Taylor and Tyson Dennert; and Jim Hansen's son, Jake, and grandson, Houston, said Travis Garza, president of the wellness company Kyäni, in a Facebook post Sunday.
Two of Kirk Hansen's sons also died in the accident, along with two of his son-in-laws. They were transported to hospitals in Sioux Falls, South Dakota.
The Hansens were prominent members of the Idaho Falls community as executives with petroleum and oil vendor Conrad & Bischoff, Kyäni and gas station chain KJ's Super Stores, according to East Idaho News.
The statement did not indicate why the family was traveling, but it linked out to a story on EastIdahoNews.com that reported the family had gone hunting in South Dakota. Inclement weather was making travel to the site hard, he said.
The Swiss-made turboprop carrying the family was destined for Idaho Falls Regional Airport in the southeast portion of Idaho, Federal Aviation Administration spokesman Lynn Lunsford said.
Kirk and Jim Jr. Weather will be among several factors they will review, although no cause for the crash has been determined, Knudson said.
