A mass shooting in River North Wednesday night and another one that wounded four people on the city's South Side early Thursday morning are stark reminders that violence can happen anywhere in the city. The police superintendent offered assurances Thursday that the strategic plan is one that is city-wide.

Chicago Mayor Brandon Johnson and Police Superintendent Larry Snelling gave an update about a River North mass shooting that killed four people and injured 14 others, while also sharing the safety plan for the July 4th weekend.

Two men and two women were killed, all in their 20s, police said. 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.
