Four people were killed and 14 others wounded in a "deplorable and cowardly" mass shooting in Chicago on Wednesday night, according to the police superintendent.

The drive-by shooting apparently happened as people left Artis Lounge nightclub following an album release party for rapper Mello Buckzz.

At least seven people were injured in a shooting in Chicago’s Back of the Yards neighborhood Friday night. According to police, two male suspects approached a group of people who were standing outside in the 4800 block of South Justine at approximately 11:11 p.m. The two suspects then opened fire, striking multiple victims.
