Memorials grow as Highland Park community remembers the victims of July 4 parade mass shooting

In the heart of Highland Park, Illinois, a community has been gathering in mourning, placing flowers, messages of remembrance and American flags at the scene of yet another mass shooting in the US.

Yellow barricade tape stretches down the sidewalks along Central Avenue, the main route for a Fourth of July parade Monday morning that was shattered by gunfire. Seven people were killed and dozens were wounded as a man fired a semi-automatic rifle from a business rooftop at crowds below before fleeing, authorities say.

Robert E. Crimo III, 21, who was arrested later Monday in connection with the shooting in suburban Chicago, admitted to authorities he was the gunman, prosecutors alleged Wednesday during a court hearing where a judge denied Crimo bond.

Crimo will face additional charges for those he wounded, along with the seven counts of first-degree murder already filed, Lake County State's Attorney Eric Rinehart said.
