VICKSBURG (WKZO) -- A portion of the former Fox Paper mill on Maple in Vicksburg caught fire Friday morning and was gutted by a three alarm fire that drew trucks from ten fire departments in Kalamazoo and St. Joseph Counties.  The building has had several uses since it was a paper mill, but apparently it had most recently sat vacant for a decade.  A damage estimate has yet to be released and investigators are still looking into the cause of the blaze.
