RANCHO CORDOVA, Calif. (AP) - Federal investigators are probing
the cause of a deadly Christmas Eve home explosion in a Sacramento
The National Transportation Safety Board is expected to focus on a suspected leak in an underground natural gas pipeline in the blast that killed 72-year-old Wilbert "Bill" Paana in his Rancho Cordova home.
Paana's daughter, 44-year-old Kim Dickson, and her 17-year-old daughter, Sunny Dickson, were critically injured.
University of California, Davis Burn Center spokeswoman Susan Mar-Schwab says the mother remained in critical condition on Monday. Catherine Curran, a spokeswoman for Shriners Hospital for Children, says the teenager is in good condition.
Three other people were treated for less severe injuries.
NTSB officials planned a Monday evening update on their investigation.
