Excerpts from centralillinoisproud.com:

A firefighter was hospitalized with minor injuries after an overnight arson that fire broke out around 12:45 a.m. at 911 and 913 W. Third Street in Peoria. When firefighters arrived at two-and-a-half-story duplex, flames were visible from both floors and the attic space.

There was a partial collapse of the second floor, and one firefighter fell through the floor sustaining minor injuries. He was transported to a local hospital.

It took crews nearly four hours extinguish the fire. An investigator deemed the fire to be arson.

Officials called for an emergency demolition due to the structural instability of the building.
