A woman who was hospitalized following a fire at a North Philly rowhome that killed her 3-year-old daughter, has died, officials said.

On Thursday morning, a Philadelphia Fire Department officials confirmed that the mother of the child that was killed in a fire Sunday at a rowhome along D Street in North Philadelphia had died due to injuries she suffered in that incident.

Officials have not yet released further identifying information on the woman or her daughter.

Fire crews were busy early Sunday after a rowhome along D Street in Philadelphia’s Fairhill section, officials say. No injuries were initially reported. 

Just Wednesday, fire officials said, firefighters were in the community near where the deadly fire occurred in order to share and install fire alarms.

Officials said another child and another adult were hospitalized as a result of Sunday’s fire.

Preliminary investigation into the incident suggests the fire was started by a lithium-ion e-bike battery located in an upstairs bedroom, officials have said.

But, an investigation into this deadly incident remains ongoing.
