Jury selection is underway for the trial of the man accused of opening fire on a suburban Chicago Independence Day parade and killing seven people in 2022. Jurors reported to the courthouse in Lake County for questioning on Monday. Jury selection is expected to last several days with opening statements next week. There have been several delays during the case, partly because of the erratic behavior of the defendant, Robert Crimo III. He has been charged with 21 counts of first-degree murder, among other charges. He has pleaded not guilty. The trial is expected to last about a month with testimony from survivors and police.
