Excerpts from the ChicagoTribune.com:

About 7:30 p.m. Sunday evening (3/26/17), Chicago firefighters responded for fire in a vacant structure at 6159 West Dickens Avenue  on the city’s Northwest Side. The response was soon raised to a box alarm.

By 10 p.m., the fire was struck out. One firefighter was taken to a hospital to be treated for minor injuries.

This from José Guillén:

Here are a few cell phone camera shots of the Still & Box at the old Zenith TV and radio factory.  I grew up in the neighborhood and was visiting my parents when I caught wind of this going on. Thanks.
