An investigator for the state fire marshal's office has determined a late Saturday night house fire in Cullison was intentional.

An investigator from the Kansas State Fire Marshal’s office has determined that the cause of a late Saturday night house fire in Cullison is incendiary indicating the fire was intentionally set and a basis for arson. A joint operation is under way in this case.

“This is an open investigation and we are working with the Pratt County Sheriff’s Office,” said Rose Rozmiarek, chief of investigations for the state fire marshal’s office.

Firefighters were called to 110 West Central in Cullison at 9:57 p.m. Saturday, Aug. 16. First firefighters on scene said smoke was coming from the structure. Firefighters entered the one story house and found one room on fire. The fire was confined to that room and was quickly extinguished, said fire Lt. Mike Adams.

The house residents were not home at the time of the fire and no one was injured.

Pratt County Sheriff’s Deputy Cole Schmidtberger said the state fire marshal had been called to the scene to investigate the fire. Both Schmidtberger and Adams declined to make further statements about the fire.

Township 9 firefighters remained on scene with Schmidtberger to secure the scene. 

Firefighters from Township 9 Cullison, with assistance from a couple of firefighters from Pratt and Township 12, fought the fire.
