Watch: Why was the US execution of Christa Pike halted?

Christa Pike, a Tennessee woman who was convicted of murder in 1996 and sentenced to death, had her scheduled execution stopped just before it was set to occur. If carried out, Pike would become the first woman executed in Tennessee in over two centuries. Her defense attorneys argue that given her documented history of childhood trauma including sexual abuse, abandonment, and neglect, she would not receive a death sentence if tried as a teenager under current standards.
