Sept. 23 — They were normal Texas families, doing normal things at home: napping on the couch; rinsing off in the shower; flipping on the light.

More than two dozen homes across North and Central Texas have blown up since 2006 because of leaking natural gas, an investigation by The Dallas Morning News found. Nine people died; at least 22 others were badly injured.
