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.

A drive-by shooting in Little Village, Chicago, left four people injured, three critically. The incident occurred early Saturday when a dark SUV fired at a parked car. No arrests have been made.
