The Minneapolis man accused of shooting a man in the head at a funeral last month on the Fond du Lac Reservation is now facing federal charges.

Shelby Gene Boswell, 28, was indicted Wednesday on one count of being a convicted felon in possession of a firearm, one count of possessing a firearm in a school zone and one count of discharging a firearm in a school zone, as the Head Start building is within 1,000 feet of Fond du Lac Ojibwe High School.

On Oct. 18, Boswell entered the gymnasium of the Fond du Lac Head Start building at 33 University Road in Cloquet. He walked behind his sister and her boyfriend, Broderick Boshay Robinson, 45, of Minneapolis and used a rifle to shoot Robinson in the back of the head, according to a criminal complaint filed last month when Boswell was charged separately in State District Court in Carlton.

Those Oct. 21 charges were dropped because of the federal indictment, Carlton County Attorney Lauri Ketola said in a news release Friday afternoon.

"Federal prosecution provides the greatest consequences for Mr. Boswell's alleged crimes," Ketola said. "As a result of the federal indictment, State charges have been dismissed at this time. The (Carlton County Attorney's Office) is committed to prosecution that maximizes the long-term safety of our community."

The state charges included first-degree assault–great bodily harm, second-degree assault–dangerous weapon, third-degree possession of drugs, fifth-degree possession of drugs, possession of a firearm despite being convicted of a crime of violence, and introduction of drugs into a jail.

Robinson, the victim of the shooting, was released from the hospital the same day of the incident. After being shot in the head, Robinson ran out of the gymnasium while mourners disarmed and briefly restrained Boswell, according to the criminal complaint.

The shooting caused lockdowns at the nearby school, tribal offices and clinic for several hours. No one else was injured.

Boswell has been previously convicted of violent crimes, including fifth-degree assault and second-degree assault involving a baseball bat on the Fond du Lac Reservation in 2010, as well as a 2015 third-degree assault in Bemidji resulting in substantial bodily harm.
