WAUKEGAN, Ill. — The trial of the man accused of opening fire at a Fourth of July parade in the affluent Chicago suburb of Highland Park ended almost as quickly as it began Monday when the suspect surprised the courtroom by pleading guilty. Robert “Bobby” E. Crimo III, who faced 69 counts of murder and attempted murder stemming from the July 4, 2022, mass shooting, entered the plea shortly before opening statements were supposed to get underway.
