Chicago firefighters battle a raging blaze for hours in the bitter cold temperatures at an historic building in Lincoln Park.
The fire erupted at the Mulligan School at Sheffield and Willow around 1 a.m. Tuesday. The flames raced through the upper floors. Firefighters tried to stop the flames from spreading inside the building, but two security dogs interfered with their efforts.
The building was being turned into condos, but it may have to be demolished.
The building dates back to 1890.
Residents say if the building is torn down, it would be a real loss for the neighborhood.
"I think it would be terrible. It's a gorgeous building," said one woman.
No one was injured. The security dogs survived.
Heavy icing on "L" tracks and power lines lead to service disruptions for the CTA's Brown and Purple lines, and ComEd.
An investigation is underway into what sparked the fire.
