Family's house destroyed in Texas blast

Anderson Cooper meets a family left homeless following Wednesday night's fertilizer plant explosion in West, Texas. They had lived in the destroyed house, which was 300 yards from the plant, since 1968.

"I never heard a blast like that," says Willie "Pee Wee" Zahirniak. He tells Anderson that he and his wife weren't in their home during the incident, and they credit their young grandson for getting them out and saving their lives.
