Investigative journalist Joe Sexton looks into a 2002 double homicide case in Kansas after receiving thousands of emails from Eileen Umbehr, a homemaker turned citizen sleuth. Eileen and her husband Keen are convinced that Dana Chandler, the woman accused of killing her ex-husband and his girlfriend, did not commit the crime and devote their lives to fighting for Chandler’s innocence. This three-part documentary series examines the polarizing murder case that spanned more than two decades and captured national attention, exploring the conviction, the overturning of the verdict, the retrial, and the unexpected twists that followed.
