Oklahoma authorities say three would-be burglars have been fatally shot by a homeowner's adult son who was armed with a rifle.

The Wagoner County Sheriff's Office received a call around 12:30 p.m. Monday from someone inside a home who told dispatchers that people had broken into the house and that shots had been fired.

Deputy Nick Mahoney says officers arrived to find three men fatally shot. The neighborhood is in an unincorporated part of the county about 20 miles southeast of Tulsa.

Mahoney says the men were wearing black clothes, gloves and masks when they forced their way in through a back door. He says there's no reason to believe the son knew the intruders and that investigators are treating the case as a home invasion.
