A criminal complaint filed in San Antonio alleges that 26-year-old Ivan Harrison Hunter is a member of the Boogaloo Bois, a loosely organized group that espouses a violent anti-government philosophy. It accuses Hunter of driving to Minneapolis between May 27 and 28 with the intent of participating in a riot.

Federal agents reviewed a video taken on the night of May 28 that shows an individual, later identified as Hunter, firing 13 rounds from an AK-47 style semiautomatic rifle into the Minneapolis Police Department’s Third Precinct building. Prosecutors allege at the time of the shooting there were other individuals, believed to be looters, still inside the precinct building.

Law enforcement recovered discharged rifle casings from the scene that are consistent with an AK-47 style firearm. A person described as a “cooperating defendant” by federal prosecutors has identified the alleged gunman from a screen grab captured at the scene as Hunter.
