CHICAGO (AP) — The upbeat mood in a busy Chicago neighborhood known for its restaurants and nightlife quickly turned into horror late Wednesday as shots were fired at a crowd from a fast-moving vehicle, killing four people.

Gunfire from a passing car ripped into a crowd of partygoers in the River North neighborhood, the police said.

Four people were injured, three critically, after a drive-by shooting in the city’s Little Village neighborhood early Saturday morning.
