Texas True Crime: Andrea Yates | Full Documentary

On June 20, 2001, Andrea Yates drowned her five small children one by one in the bathtub of her Clear Lake home. Yates, who is now 56, was tried twice for the deaths of her children. In 2002, she was convicted of capital murder and sentenced to life in prison. Her conviction was later overturned based on false testimony. A second trial in 2006 resulted in a verdict of not guilty by reason of insanity. Yates was sent to Kerrville State Hospital, a mental health facility, where she remains today. She has now spent a third of her life institutionalized. Twenty years after the tragedy, ABC13's Jessica Willey is hearing from those who saw the case unfold in the ABC13 Original "Andrea Yates: 20 Years Later".
