Officials say the funeral mass for Lt. Matthew LeTourneau will be held Friday at the Cathedral Basilica of Saints Peter and Paul in Philadelphia.
The 11-year veteran was pulled from the home on Saturday by fellow firefighters and taken to a hospital, where he was later pronounced dead.
A person who lived in the home also was killed in the blaze. Two other firefighters were treated at a hospital for undisclosed injuries that were not believed to be life-threatening.
LeTourneau joined the fire department in 2007 and was promoted to lieutenant in 2015.
The city’s mayor, fire commissioner and LeTourneau’s brother are expected to officer remarks.
