Paducah, KY – Some Irvin Cobb Apartment tenants in Paducah have moved back into the building as of yesterday. About 40 of the 92 residents living on the fifth through the ninth floors returned to their apartments. Contractors are still working around the clock to clean up the lower floors. The building's fire sprinkler line froze and ruptured over the weekend, flooding the building and forcing residents to evacuate. The line freeze may have been caused by windows left open for several days in a fourth floor room. Residents tell the Paducah Sun they believe a building staff member opened the windows last week to air the apartment out after a man suffering from a long-term illness was found dead. Irvin Cobb staff deny the allegations.
