CHICAGO (CBS) — A woman was hospitalized Monday night in serious-to-critical condition after being struck by falling debris from a building at State and Randolph Streets.

The aluminum debris did not fall far.  It was part of the first floor facade of the former Loehmann’s store on the ground floor of the Joffrey Tower at 151 N. State St.       

But it was big — a vertical, triangular piece about 15 feet tall, six inches wide, and anywhere from half an inch to three inches thick. It’s unclear where the debris hit the woman.  

Paramedics were on the scene within moments of the time she was struck at 5:45 p.m.  They transported her to Northwestern Memorial Hospital.

The woman was reported in serious to critical condition, fire officials said.

The building is not old; it was completed in 2008.
