Updated at 3:30 p.m. Saturday: Revised to note evacuation has been lifted.

Fire investigators and utility inspectors are working to determine what caused a Dallas home to explode Friday morning, killing a 12-year-old girl and injuring several others.

The blast was reported about 6:30 a.m. in the 3500 block of Espanola Drive, between Webb Chapel Road and Marsh Lane in northwest Dallas, Fire-Rescue spokesman Jason Evans said.

Half a dozen firetrucks and ambulances quickly converged on the neighborhood north of Bachman Lake and found the family who lived in the shattered home already outside.

A witness described seeing family members crying in the yard, huddled around the girl. Paramedics performed CPR as she was rushed to the hospital, Evans said.

There was no fire when Dallas Fire-Rescue crews arrived.

"The attention immediately went to the girl," Evans said, "and I don't recall hearing anything about the fire."

The girl did not survive, school trustee Miguel Solis said. She was identified as Linda Rogers.

What sparked the explosion remains under investigation, but it was believed to be fueled by natural gas. Atmos Energy had several crews at the scene investigating.

Atmos issued a written statement to say it was working with Dallas Fire-Rescue and planned to share a "detailed assessment" of what happened.

Inspectors were going house to house in the blocks surrounding the blast, informing residents about the situation and telling them to evacuate. The evacuation was lifted Saturday afternoon, but gas service had yet to be restored to the homes.

Atmos said it was working to provide lodging for those people affected. Residents who need help getting assistance or are looking for updates on service restoration can visit atmosenergy.com/alerts or call 972-964-4191.

The explosion also triggered the evacuation of about 700 students at nearby Foster Elementary School.

Students in pre-kindergarten through second grades were taken to Cary Middle School. The remaining students were taken to Thomas Jefferson High School.

The force of the blast blew the home off its foundation, and the roof collapsed. The front yard was littered with insulation and other debris from the blast.

But it was the girl's death that troubled neighbors the most, as well as the potential for more trouble to come, after two previous fires this week in the same block.

"We are deeply saddened by the death of the young girl at 3534 Espanola Drive this morning," Atmos Energy president Mike Haefner said in the statement. "We express our sincere heartfelt condolences to her family."

Neighbors said the family had recently moved in after renovating the house for months. One neighbor said the family still hadn't unpacked all the boxes.

Two other house fires were reported in the neighborhood this week.

On Wednesday at about 6 a.m., a fire that was believed to be fueled by natural gas broke out in the 3500 block of Durango Drive, a block away. One person went to a hospital for treatment.

On Thursday, a kitchen fire was reported on the same block. A man was cooking on the stove when he was burned by a flare-up that spread.

One neighbor, Ignacio Aguilar, described Friday's explosion like a clap of thunder. By the time he made it outside, firefighters were already at the house trying to help the family.

Aguilar returned to the house on Espanola around 9:30 a.m. to get a better look at the damage in the daylight. The roof had sunk in even more, and rain had dampened the debris.

The thought of three house fires in three days seemed to be on the minds of everyone in the neighborhood.

Could one of their homes be next? Aguilar wondered.
