A week after shocking mass shooting outside River North lounge, links to city’s worst gang feud have surfaced again.

Cook County Crime Stoppers announced Monday that they are offering a cash reward of $10,000 for information leading to arrests in a mass shooting that left four people dead and 14 wounded outside the Artis Restaurant and Lounge in Chicago's River North neighborhood last week.

It happened outside a restaurant as people were leaving an album release party for Chicago rapper Mello Buckzz. Another mass shooting happened at a club that operated from the same address in 2022.

The mass shooting in River North that claimed four lives and injured 14 others was the start of a violent Fourth of July weekend in Chicago. The latest: There were at least three mass shootings in Chicago from Wednesday to Saturday night.

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.

Chicago's Fourth of July weekend was the least violent in six years, with nine fatalities despite multiple mass shootings.
