CHAMBERLAIN, SD (Ben Caxton) — Federal investigators are expected to arrive Monday at the South Dakota site where nine members of an extended Idaho family were killed in a plane crash. Twelve people were aboard the Pilatus PC-12 bound for Idaho Falls when it crashed within a mile after takeoff in Chamberlain about 12:30 p.m. Saturday. The crash killed brothers Jim and Kirk Hansen, their father, Jim Hansen Sr., 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. Three people survived the crash and are hospitalized identified as Kirk’s son, Josh, and Jim’s son, Matt, and son-in-law, Thomas Long. The Hansens were executives with Kyani, which markets nutritional, health and wellness products, as well as with petroleum products distributor Conrad & Bischoff and KJ’s Super Stores. Reports say they had been on a hunting trip to South Dakota, one of the nation’s top destinations for pheasants. Weather will be among several factors investigators will review, although no cause for the crash has been determined.
