Powell told ABC News that he had no idea what the images were, and wondered why police were bringing them up now, two years after they were reportedly found on his computer. He said he did not remember any inappropriate images at all on his computer from that time.
Powell also said he regretted the fraught relationship between his wife's parents, Chuck and Judy Cox, and himself in the years since Susan's disappearance. He said he was actually happy that his children had their maternal grandparents in their lives, a significant reversal from earlier statements in which he disparaged the Coxes and said they were poisoning the children with hatred for him.
Kids Claim Susan Powell Was in the Trunk
According to an attorney representing Powell's in-laws Chuck and Judy Cox, one of the young sons was beginning to verbalize details about the night their mother disappeared, including an allegation that Susan was in the trunk of the family car, and disappeared shortly after they arrived at their campground.
"They were beginning to verbalize more," Steve Downing said today. "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."
The boys were 2 and 4 at the time of their mother's disappearance.
In his final conversation with ABC News before his death, Powell continued to talk about his wife, Susan, in the present tense as if she were still alive. Susan has not been seen or heard from since 2009, but police have never found evidence that she is dead.
Josh also repeated his claim that his wife was a very sexy, flirtatious person. Powell's father Steve Powell had even claimed she had flirted with him.
During his conversation with ABC News last week, Josh Powell said he didn't visit his father in jail very often, and said was disappointed that his father claimed to be receptive to Susan's alleged flirting.
In the summer of 2011, police searched the Washington state home where Josh and Steve Powell lived with the two boys. Steve was subsequently arrested and charged with child pornography and voyeruism.
The explosion Sunday at Josh Powell's home was purposeful, according to Pierce County, Wash., authorities. The social worker who brought the children to a supervised visit at Josh's house was locked out of the home by Powell. She immediately smelled gas and called her supervisor to report it.
Shortly after, the home exploded.
Josh Powell's lawyer, Jeffrey Bassett, said he received an email from his client minutes before the explosion that said "I'm sorry, goodbye," but he didn't see it until two hours later, when he was informed of the blast.
Bassett told AP he knew his client was upset about being denied custody of his sons at a court hearing last week, when he was ordered to undergo a psychosexual evaluation and polygraph test in order to get them back.
