RAY, Minn. - Sheriff's officials in northern Minnesota say a home invasion has ended in deadly gunfire.

Authorities say 34-year-old Benjamin Beaudolin of Mendota Heights came to the door of a home in Koochiching County asked for help Saturday just before 6 a.m. Saturday. When 72-year-old Ethal Himes opened the door and allowed him to come in, the suspect assaulted her, throwing Himes to the ground and pounding her head on the ground. At that point Himes' 48-year-old son Bradley Himes stepped in with a gun and fatally shot Beaudolin.

A Koochiching County deputy arrived and the suspect was taken to Rainy Lake Medical Center where he later died from his injuries.

The Koochiching County Sheriff says the Himes home was not the first place Beaudolin entered. Just before the fatal shooting deputies responded to a call of a break-in and assault. The home owner told deputies that a man broke into his home through a locked door. At that point the homeowner woke up, grabbed a shotgun and engaged in a struggle with the intruder, eventually breaking off the stock by hitting the suspect over the head. The intruder, later identified as Beaudolin, fled the scene in his vehicle.

Koochiching County Sheriff's Capt. Jon Froemke says Beaudolin has no history of criminal activity, and was at a resort for a friend's wedding when he broke into the two homes.

The Minnesota Bureau of Criminal Apprehension is assisting in the investigation. The home invasion happened at a home in Ray, which is about 20 miles southeast of International Falls.
