North Dakota's state fire marshal is investigating a house explosion west of Williston that left a Montana man hospitalized with burns.
Williston Rural Fire Chief Dave Benth says neighbors called 911 after witnessing the blast Monday evening. The Rural Fire Department and the Williams County Sheriff's Department responded.
Benth says one person was taken to a hospital to be treated for severe burns.
The Daily Inter Lake in Kalispell, Mont., reports Casey Malmquist of Whitefish, Mont., was hospitalized in stable condition Wednesday in St. Paul, Minn. Janene Adams, office manager at Malmquist Construction, says Malmquist suffered second- and third-degree burns and underwent surgery Tuesday.
