It seems a little incongruous that E! Entertainment Television is airing an hour about the Susan Cox Powell case - there's no Hollywood tie (yet) and it hardly seems entertaining.
Nonetheless, E! Investigates (9 p.m., E!) is going to retell the story of her disappearance; of the search; of how her husband, Josh Powell, killing his young sons and himself; and of her father-in-law, Steve Powell, being convicted on multiple counts of voyeurism.
Among those interviewed for the story are The Salt Lake Tribune's own Melinda Rogers.
