A woman was killed and five other people were hurt when gunfire erupted early Sunday at a large outdoor gathering on Chicago's West Side – one of three separate shootings to occur in the same neighborhood in fewer than three hours, according to police.

Four people were wounded, including two teens, in a mass shooting overnight on the city's West Side. Chicago police said around 1:47 a.m. Sunday, officers responded to a person shot call in the 4500 block of West Wilcox Street, and found multiple gunshot victims.
