At least 13 people were shot in a shooting in Chicago Monday night, police said.   

  It happened around 9:30 p.m. as a crowd gathered at the corner of California Avenue and Polk Street, according to Chicago Police Superintendent David O’Neill Brown.   

  One person was also hit by a car at the scene, Brown said at a news conference.   

  Police earlier said 14 people were shot, but revised the number to 13 in a statement early Tuesday.   

  Among the victims were children, including a 3-year-old boy, an 11-year-old girl and a 13-year-old boy, the police statement said.   

  The victims were taken to several area hospitals in conditions ranging from non-life-threatening to critical, the inspector said.   

  A group of people were meeting on the corner for a vigil when the shooting occurred, Brown said.   

  Others may also have gathered for various other reasons, Brown added.  “It’s a very common corner where people gather and have different meetings and gatherings.”   

  Two people traveling in a dark SUV opened fire on those on the corner and then drove away, police said in the statement.   

  Investigators obtained video from the scene, which shows the shooting happened in a matter of seconds, according to Brown.   

  He encouraged anyone with knowledge of the incident to contact law enforcement or leave an anonymous tip with CPD Tips.
