Chicago Police say five people were wounded during a shooting outside a church on the city's North Side.
Authorities initially said one person died in Monday's violence. But Tuesday, a police spokesman said a 21-year-old man was instead critically wounded after being shot in the head in the Uptown neighborhood.
Four other men were hospitalized for gunshot wounds and were in either stable or good condition. Police say the shooting may have been gang related.
Witnesses say they heard about 20 shots, which they initially thought were fireworks. Then at least one of the victims stumbled to the stairs of Uptown Baptist Church, where volunteers were serving dinner to the area's homeless people.
The shooting follows a violent weekend that saw at least six people killed and another 27 wounded.
