ABC’s “20/20″ and NBC’s “Dateline” will go head-to-head Friday night with reports on the same topic: the story of Josh Powell, the Utah man who killed himself and his two young sons in an explosion on Sunday. Powell had been implicated in the disappearance of his wife Susan in late 2009.

On “Dateline,” Keith Morrison talks with Powell’s in-laws, Charles and Judy Cox, as well as his sister, Jennifer Powell. The “20/20″ report, anchored by Chris Cuomo, will focus on the events leading up to the tragedy. Jennifer Powell sat for an interview with ABC’s “Good Morning America” earlier this week. And today Cuomo talked with the social worker who dropped off the Powell boys at the home last Sunday.

“He caught my eye, his shoulders were slumped. He had a sheepish look,” Hall told ABC News. “He just shrugged his shoulders and slammed the door.”

Both shows air on Friday at 10pmET. We’ll have the overnight ratings for you on Saturday.
