Olmsted County Sheriff’s Office Captain Tim Parkin says deputies responded to the initial threat, which was targeted towards a business around 1:45 p.m.
The U.S. Attorney's Office in April announced a nine-count indictment against five individuals, including 33-year-old Erick Emilio Diaz-Aguilar of Rochester.
The shooting happened on the morning of December 12 as the Stewartville High School Wrestling team was loading a bus for a trip to Grand Forks, ND for a wrestling match.
