A sheriff's deputy was killed in a shootout with two suspects during a traffic stop early Tuesday near Three Forks, Montana.

Broadwater County Deputy Mason Moore was chasing an SUV on U.S. Highway 287 when dispatchers lost contact with him at about 3 a.m. Tuesday, Gallatin County Sheriff Brian Gootkin said.

Gootkin told the Bozeman Daily Chronicle that Gallatin County and Montana Highway Patrol officers responded and found the deputy dead by the side of the road.

The SUV was spotted again near Anaconda. Officers deployed spike strips in Powell County, but the driver was able to continue west on Interstate 90 before stopping about 35 miles east of Missoula.

Missoula County investigators said the passenger, identified as 38-year-old Marshall Barrus, got out of the SUV and begin firing at officers. He was shot in the head and taken to the hospital. His condition was unclear.

The driver, the shooter's father, was arrested on suspicion of deliberate homicide. He was identified as 61-year-old Lloyd Barrus.
