Nearly 300 Morton High School graduates walked across the stage during the commencement ceremony at the Pavilion at Wolf Lake Memorial Park on Saturday afternoon.

Three suspects who were being sought by North Dakota law enforcement after a chase from Sioux to Morton counties were apprehended Monday evening, authorities said.

The protest is scheduled for noon-2 p.m. Saturday at Morton Park, located along Lincoln Avenue/Illinois 16 a block north of Eastern Illinois University's campus.
