Fire investigators are looking into a fire Thursday that damaged an assisted-living facility. The emergency call went out at 3:30 p.m. at Racine Commons, 8500 Corporate Drive, just north of Highway 20, and escalated to a second alarm for equipment and personnel. South Shore Fire Battalion Chief John Radewan said as soon as firefighters got to the scene they saw smoke and flames coming from the northeast corner of the H-shaped housing complex, which is west of Stuart Road and east of 90th Street.
