CHARLOTTE, N.C. (AP) – Fire officials say a gas leak led to the fire and explosion that leveled a house in North Carolina, killing a woman inside.

Fire Marshal Jonathan Leonard of the Charlotte Fire Department told a news conference Wednesday that the gas leak in the home appeared to be accidental but he couldn’t provide any additional details of what happened.

Charlotte-Mecklenburg police identified the woman in a report released Wednesday as 58-year-old Rania Karam.

Battalion Chief Matt Westover said it was her husband, Jebran Karam, who called 911 and later directed firefighters to where his wife was located in the shattered home after Tuesday’s blast. Jebran Karam was pulled from the rubble and taken by helicopter to a hospital for treatment of life-threatening injuries.
