(Richmond, IN)--The identities of the two people killed in a fire at Interfaith Apartments in Richmond Monday afternoon had not been released early Tuesday morning. Fire broke out at just after 5 o’clock on the building’s fifth floor. Virtually all of the city’s firefighters responded, but heavy smoke made it difficult to determine where the smoke originated. Two people found in the hallway died as a result. Five other residents of the apartments were taken to Reid Health to be treated for smoke inhalation. Two firefighters were also treated. "Our firefighters were released and returned to duty," said Battalion Chief Charlie Bartlett. The five residents are expected to be okay. The state fire marshal’s office will be at the scene today looking for a cause. Most of the residents of Interfaith Apartments were allowed to return Monday night. About 30 residents of the fifth and sixth floors were with relatives or friends Tuesday morning. About six other residents were being helped by the Red Cross. During the fire, Reid Health issued a mass casualty plan in which many extra medical personnel were called. A triage center was set up in a neighboring building. Firefighters carried many elderly or disabled people down multiple flights of stairs after having gone door to door to clear the building. "There were some that needed assistance and were wheelchair bound," Bartlett explained. Firefighters from other communities arrived to help cover the city’s other runs.
