Federal team investigating deadly Dallas house explosion

Federal authorities are investigating a suspected natural gas leak that caused an explosion a newly renovated house in Dallas, killing a 12-year-old girl and injuring four other members of her family.

The National Transportation Safety Board said it was sending a three-person team Sunday to look into the blast.

Firefighters Friday found the home shattered but no fire. Four injured people were in the front yard and one of them was holding the unconscious girl. Authorities say Linda Rogers was pronounced dead at a hospital.

Two other gas-related problems were reported last week in the neighborhood where a construction crew has been working.

City officials on Saturday lifted a mandatory evacuation order for about 300 families in the area but natural gas service was suspended.
