Liberal Fire Department investigators started working the fire scene on Monday morning and continued throughout the day attempting to determine a cause of the fire from Sunday evening. LFD investigators met with insurance fire investigators on Tuesday. Through efforts of both parties, the official cause of the fire will be listed as undetermined. All accidental and natural causes have been eliminated; however, due to the extensive damage and destruction of any potential evidence, a finding of anything other than undetermined is not possible at this time. Interviews with potential witnesses will continue and investigators encourage anyone with information regarding the fire to contact Deputy Chief Skeety Poulton or Fire Inspector Cody Regier at the Liberal Fire Department at 620-626-0128.
