A woman died after a fire Sunday morning at an apartment building in downtown Indianapolis.

The fire broke out around 5 a.m. Residence Lucille Raines at 947 Pennsylvania St. The woman, whose name has not been released, had evacuated but returned to her apartment twice to collect her belongings, according to the Indianapolis Fire Department.

She didn’t make it the second time around.

The department said the fire was accidental, although investigators have not determined its cause. The fire appears to have started on the fourth floor, where the victim lived.

Several residents were examined by paramedics, but no one needed to be taken to hospital. No other injuries were reported. The other 45 residents of the building returned to their apartments safe and sound.

The fire department reminds everyone not to attempt to return inside a burning building to gather personal effects or pets.

“Get out and stay out. The toxic effects of the smoke will render you unconscious within minutes and can prove fatal – as evidenced by today’s unfortunate death. Our thoughts are with all those affected by his loss” , the fire department said.

The Lucille Raines Residence, owned and operated by United Methodist Women of Indiana, provides homes and programs for people recovering from alcohol and drug addiction. The six-story building was built in 1977 and houses up to 49 residents, according to its website.
