The man charged with killing seven people at a Fourth of July parade in suburban Chicago asked to again be represented by public defenders after firing them last month and insisting on handling his own case. Robert Crimo III is charged with 21 counts of first-degree murder — three counts for each person killed — as well as 48 counts of attempted murder and 48 counts of aggravated battery. Last month, 23-year-old Crimo told a judge he wished to represent himself at his trial, and asked to move his court date up by a year, to February of this year rather than next.
