Investigators with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives say they have narrowed down the origin of last week’s fire at the former Weaver Organ and Piano Company.
The investigators believe the fire started on the first floor of the four-story building at Broad and Walnut streets, but they have not yet determined the cause.
The ATF said the fire was not intentionally set, and they have identified potential accidental causes. A handful of electrical items such as air conditioners and wiring has been sent to a laboratory for further testing.
“We have a four-story building that did collapse,” ATF Special Agent Don Robinson said Friday at a news conference. “That makes it very difficult for the investigators who are looking for burn patterns and indications of fire dynamics inside the structure, and it’s made all the more difficult when the building collapses.”
The ATF has completed its on-site investigation and handed over its findings to the city’s police and fire departments.
Two York firefighters died in a partial building collapse the day after the March 21 fire. Ivan Flanscha, 50, of Red Lion, and Zachary Anthony, 29, of York, were putting out hotspots when the fourth floor collapsed beneath them.
Two other city firefighters were injured.
