The blaze started around 4 a.m. on 52nd Avenue North at Louisiana Avenue.

A grandmother, Patricia Patton, 46, and her 2-year-old granddaughter are also in critical condition at Vanderbilt Medical Center.

Firefighters found the victims in a hallway of the burning home. They performed CPR outside the home until paramedics could transport them to a hospital.

The child who died was identified as Angel Bennett. The injured 2-year-old's name is Crystal Bennett. The injured child was breathing on her own, according to her uncle.

Family members sifted through what remained of the home on Thursday afternoon.

"Tell your family you love them. Don’t forget, because you might not have it in a minute to call. Call now. Call every day," said relative Karen Laquay.

Two firefighters were also injured fighting the blaze. One firefighter was taken to the hospital with injuries to his hands, while the other firefighter was not transported to the hospital.

Two family pets also died in the fire.

Fire investigators said they believe the fire started in the kitchen and possibly started by cooking that was left unattended.

Fire Department Offers Free Smoke Detectors

The Nashville Fire Department said the home did not have a smoke alarm.

Thursday’s death was the second time in two weeks that a child has been lost to a fire. On July 11, a 9-month-old died from injuries he suffered in a house fire.

"That stresses the importance of having an early notification system, especially when fires break out when people are asleep," said Chief Kim Lawson of the Nashville Fire Department.

"That’s not to say that"s why they died. But it's important to say today, you should have (smoke detectors) to increase your chances of living through a fire," Lawson said.

They urge smoke detectors to be installed on all floors of a home and near sleeping areas. The fire department is issuing free detectors to anyone who needs one. Simply call 862-5282 for a detector.
