The Last Defense

Darlie Routier has been on death row in Texas for more than 20 years. But did the mother of three kill her two young sons in June 1996, or had she survived a stabbing by the same intruder she claimed killed the boys? This new, seven-part series, co-produced by actress Viola Davis, reopens the Routier file and a second death-penalty case in Oklahoma to shed light on flaws in the criminal justice system that call into question its capacity to decide such cases beyond a reasonable doubt. Tuesday, June 12, at 10 p.m., ABC stories. But up first is Daily Show host and South Africa native Trevor Noah. Friday, June 15, at 8:30 p.m., PBS; check local listings
