Chicago Tribune reporter Adam Sege recaps the night's crime, including a police involved shooting on the South Side, and a building fa├žade collapse in Pilsen.

No one was injured when part of the facade of a century-old Pilsen building collapsed overnight, authorities said.

About 1:50 a.m., a front wall with an air conditioner slid from a 2-1/2-story building, according to Chicago Fire Department spokesman Larry Langford.

No occupants were injured, and the building, which is more than 110 years old, remained structurally sound, Langford said.

Building inspectors will be evaluating the damage.
