Crews battled a fire around 6:30 a.m. Thursday in Madison, and authorities said a person of interest was taken into custody in connection with the fire.
When the fire was reported at 1706 Market St., it was believed a person was inside the home, according to Madison Assistant Fire Chief Dave Klee.
Crews searched the home and could not find anyone. The homeowner, a woman, was found later at a different location.
While no one was injured, Klee said the fire’s origins were believed to be suspicious and the Illinois State Fire Marshal was called for an investigation.
