After months of investigating, police believe they have arrested a person involved in multiple acts of vandalism in Steuben County. Officers say 18-year-old Gavin Willis was arrested on Wednesday,  April 3, and is facing charges of criminal mischief. They first began looking into this case last November, after a Lake Gage home was vandalized. At least four other homes were later damaged. A minor – who has not been publicly identified – had already been arrested in connection with these crimes.
