The Rochester Fire Department was called to the scene at City Blue Imaging on Scio Street near East Avenue at around 10:45 p.m.. When they got there, firefighters found heavy smoke and fire pouring out from the back. Fire crews had a difficult time trying to knock down the flames because of the intense heat, plus, the building's size, limited entrances, and a lack of windows. As firefighters worked to fight the fire from the outside, the front of the building collapsed. After hours of work, and roughly 70 firefighters on the job, the flames were under control. One firefighter suffered a minor injury..
