CHICAGO (AP) - A Chicago school building opened to students in 1890 has been gutted by fire.
The former Mulligan Elementary School in the upscale Lincoln Park neighborhood is now caked in ice after firefighters battled the blaze for several hours Tuesday.
Chicago Transit Authority elevated train service was disrupted for nearly six hours as crews removed ice from the tracks caused by water used to fight the fire.
The building was closed in the 2000 and sold by the Board of Education several years later. A developer was converting the building into condominiums.
Firefighters were confronted by two guard dogs when they arrived to fight the blaze. The Rottweilers were handed over to animal control agents.
Authorities say the cause of the fire hasn't been determined. No one was injured.
