At least 14 people – including three children – were shot in a drive-by shooting Monday night at a busy corner in Chicago where people had gathered for a vigil, and investigators are trying to find the shooters, police said.

Two people traveling in a dark SUV opened fire on Halloween night at people on the corner of California Avenue and Polk Street around 9:30 p.m. before the vehicle was driven away, police said.

A 15th person – a woman – suffered scrapes when a vehicle struck her as she tried to flee from the site, police said.

A 3-year-old boy, an 11-year-old girl and a 13-year-old boy were among those shot, police said.
