Boys Killed in Explosion Had Started to Talk About Mom

Behind the tragic explosion in Washington state that authorities say Josh Powell intentionally triggered, killing himself and his two young sons, a possible motive. The lawyer for Susan Powell's parents yesterday told the AP that Charlie and Braden, ages 7 and 5, were starting to remember things about the December 2009 night their mother disappeared—and talk about them.

"They were beginning to verbalize more," said the attorney for Chuck and Judy Cox, who had custody of the children. "The oldest boy talked about that they went camping and that Mommy was in the trunk. Mom and Dad got out of the car and Mom disappeared." Powell has maintained that he took his toddler sons to go camping on a freezing cold night, and that Susan was gone from their Utah home when the three returned. Click for more on the case.
