The man accused of opening fire on a suburban Chicago Independence Day parade and killing seven people is about to stand trial nearly three years after the attack.

In the midst of the chaos of a Chicago-area parade massacre, a woman walked up to Greg Ring and handed him a 2-year-old boy, covered in blood.

The parents of a 2-year-old boy who got lost during the July 4 parade shooting in suburban Chicago are among the seven people who were killed, authorities said as friends and family mourned their lost loved ones.
