Toledo’s Fire investigative unit is looking into the cause of two suspicious fires from overnight. A garage caught fire first early this morning near 5th and Starr Ave, then an hour later, another fire. A Battalion Chief tells 13abc the fire is at a vacant house at the corner of Starr Ave and 5th Street. Firefighters are still working to put out the fire. The FIU (Fire investigative unit) is on the scene, looking into a possible cause for both fires. No one was hurt.
