Three-story West Garfield Park building partially collapses in fire

A three-story building in West Garfield Park on the West Side partially collapsed during a Wednesday night blaze.

Authorities responded to the fire at a building in the 4300 block of Van Buren and Kostner about 10 p.m., according to a spokesman for the Chicago Fire Department. The fire was struck out about midnight.

Because the back part of the building had collapsed, authorities were not yet able to search for anyone who had been in the building, the CFD spokesman said. No injuries had been reported as of 12:30 a.m.

The cause of the fire was under investigation early Thursday.
