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

In the heart of Highland Park, Illinois, a community gathers 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.
