The sound of breaking glass could be heard early on Sunday morning as boys jumped from the windows of a Queens home that had become engulfed in flames as a result of a fire the authorities said was caused by a burning candle.

The family had not been alerted to the fire because the smoke detector in the two-story home in the quiet Springfield Gardens neighborhood did not function, fire officials said.

One of the children, 8-year-old Tighani Jones — “the baby,” as he was known — did not survive the 2:30 a.m. blaze that also injured six other people, the police said.

Two older boys were able to jump to safety through second-floor windows, neighbors said.

“I took my coat off, my sweater, and wrapped him up,” a neighbor, Dwayne Sundar, said of a boy he said was between 10 and 12 years old.
