VIDEO: A Rochester man was arrested and charged with arson in consecutive fires set on a building at East Main Street and Alexander Street, officials announced Thursday. Fire crews with the Rochester Fire Department responded to an overnight fire on 432 Alexander Street Friday and found a vehicle that had been set on fire. Video captured the moments before the blaze spread through an occupied 22-unit apartment building. Firefighters managed to contain the fire to the outside section of the structure and say no one was injured during the incident. Three days later, fire crew members were dispatched to the same building for a fire that quickly progressed to a three-alarm fire. After the fire was put out, authorities said a person was found inside Monday morning when firefighters responded to the blaze around 7 a.m.
