Robert Crimo III, now 24, is accused of firing into the crowd from a rooftop overlooking a parade in Highland Park, Illinois. Seven people died.

The man accused of opening fire on a suburban Chicago Independence Day parade, killing seven people, is about to stand trial, nearly three years after the attack. Jury selection started Monday after several delays.

The city of Highland Park plans to hold an Independence Day parade this year, the second time the north suburb has held the event since seven people were killed during a shooting at its annual parade on July 4,
