WDIO Created: April 05, 2021 05:41 PM The Duluth Fire Department is currently investigating Sunday afternoon’s fatal fire at a 3rd Street apartment building as “accidental”. This was the second fatal fire at 631 E 3rd Street within the last 9 months. "In both cases, to this point, we have not found anything that would lead us to believe that the building or any of the building's components had anything to do with these fires," explained Deputy Chief of Life Safety Jon Otis. “"The building last fall was initially condemned. There were two rooms that were mostly affected, though. The condemnation order was lifted on 6 of the 8 units until January of this year when our life safety team got back into the building and they did a re-inspection and the condemnation was lifted from all units. At the time of that inspection, everything was compliant."
