Celina firefighters take a break after battling a blaze that heavily damaged one of three buildings at Westlake Village, 1145 West Bank Road, on Thursday afternoon. Firefighters from Coldwater, Montezuma, St. Henry and Burkettsville provided mutual aid. Additionally, Rockford Fire Department provided coverage at the Celina fire station and assisted with emergency medical services. The investigation is continuing but Celina Fire Chief Doug Wolters believes the fire began outside the structure on the second- or third-story level. Investigators from the Ohio State Fire Marshal's Office are expected to return today.
