Excerpts from foxillinois.com:
The Springfield Fire Department was called to the 1300 block of West Miller around 7:30 a.m on Tuesday. When firefighters arrived, they found the house heavily involved in flames. While searching for people who may have been trapped inside, a firefighter fell through a hole in the floor into the basement. A mayday alert was immediately issued which triggered a second alarm response to the scene.
Other firefighters were able to rescue the firefighter within 15 minutes. He was taken to a local hospital with non-life threatening injuries.
The home is a total loss and the fire department is investigating the cause of the fire.
