A road rage incident ended in a shooting in Grafton, New Hampshire, Monday afternoon.

It happened on Route 4 near Lower Meadow Road.

Police say Joseph Brown, 38, and a 46-year-old driver were both headed north when the confrontation began. Then the cars hit each other and both drivers pulled over.

New Hampshire State Police Lt. Gary Prince says they're still investigating how this all started.

"There was some sort of altercation going on as they are driving on Route 4. And as a result of that, I believe the Ford Flex had passed the Escape and slammed on the brakes causing the crash. We are trying to figure out what caused the initial confrontation while they were driving," Prince said.

Police say after a small fight, Brown shot the other man in the stomach. He is expected to survive.

Brown is being charged with first-degree assault and is expected in court Tuesday afternoon.

Both men are from Grafton, but at this time police say there's no evidence they knew each other.
