Authorities say a member of the Montana Air National Guard was killed in a single-vehicle rollover crash south of Great Falls.

Montana Highway Patrol Trooper Danny Sons says the woman's vehicle hit loose gravel as it was coming around a curve on Gibson Flats Road on Tuesday afternoon. The vehicle rolled three times after the driver overcorrected.

The patrol identified the Helena woman as Doris Hagan, a member of the 219th Red Horse Squadron of the Guard.

Sons says the driver, who was the only one in the vehicle, was going too fast for the road conditions and may have been distracted before the crash.

The woman was wearing a seat belt.
