Orlando Lomax, 28, was fatally shot in Chicago on August 2, 2014. His death came during a particularly violent weekend in the city when at least two people were killed and about 22 others wounded in multiple shootings across various neighborhoods.

Police increased patrols and community groups pushed prevention efforts during that period, but the weekend underscored continuing challenges in stemming the violence.
