March 10 —  An email sent by Atmos Energy to Texas regulators reveals company workers were investigating natural gas leaks involving fires at two Dallas homes some 12 hours before an explosion at another home killed a 12-year-old girl.

The company did not evacuate residents or shut off gas lines in the neighborhood near Dallas Love Field airport until after the Feb. 23 explosion that knocked a home off its foundation and killed Linda Rogers. Three days later, the broader neighborhood was evacuated and Atmos cut service to 2,800 homes.
