20/20: Darlie Routier (9 p.m., ABC) - ABC gives us a two-hour look at the case of Darlie Routier, a Dallas housewife sentenced to death for the stabbing murder of her two young sons in 1996 — an attack she says was committed by an intruder who also slit her throat while she slept. Investigators believed she fabricated the story and staged the crime scene, but other investigators who have taken up Darlie’s cause since her conviction say she is innocent (and they are pretty convincing, in my opinion). This case was the subject of a very good ABC docu-series that aired last year called “The Last Defense” and tonight’s episode is an abridged version of Darlie’s story from that series. “The Last Defense,” executive produced by Viola Davis, looked at two questionable death row cases. The program presents interviews with Darlie, prosecutors in the original trial, Darlie’s current defense team and Darlie’s ex-husband, Darin, who believes she is innocent.
Dateline NBC (9 p.m., NBC) - “Dateline” goes two hours tonight as well, with the shocking story of 16-year-old Meghan Landowski, murdered by a classmate in her Portsmouth, Virginia home in 2008.
Wu-Tang Clan: Of Mics and Men (10 p.m., Showtime) - This new four-part documentary series looks at the group’s career, including interviews from each of the nine living members with never-before-seen archival footage and performances. The first installment starts with Robert Diggs recognizing the special way he and his friends told stories, and the group cutting the song “Protect Ya Neck.”
Reborn (PBS Masterpiece Prime) - This French crime-thriller follows felon Alexis Marceau (Bruno Debrandt), who enters witness protection and gets reconstructive surgery for a new identity and new life as construction worker Matthias Leblanc. When a judge offers to revoke Leblanc’s house arrest in exchange for going undercover with his old gang for three months, he accepts the assignment, but struggles to resist the temptations of his old life. (Please note this is airing on PBS’ streaming network, which also releases Season 2 of “The Court” and the new Belgian crime drama “Rough Justice” this month. The service costs $5.99 per month after a free 7-day trial.)
