Wednesday, September 5th, 2012 — Family members of four people killed in a grain elevator explosion last year in northeast Kansas are suing employees of Bartlett Grain Co., including its current president Bob Knief, less than five months after federal investigators pinned the blame for the blast on the Kansas City, Mo., company. The wrongful death lawsuits were filed Aug. 27 in Jackson County Circuit Court in Missouri on behalf of Bartlett employees Chad Roberts, 20; Ryan Federinko, 21; Curtis Field, 21; and John Burke, 24. They were killed along with two grain inspectors Travis Keil, 34, and Darrek Klahr, 43 when the Bartlett elevator exploded Oct. 29, 2011, in Atchison, Kan.
