Christa Pike remains unconscious days after failed execution attempt

Christa Pike remains unconscious and on a ventilator in a Nashville hospital days after surviving two doses of pentobarbital during her Wednesday execution attempt, her attorney Stephen Ferrell said Sunday. Doctors are still working to clear the lethal drug from her body, and her prognosis may not be known for several days, Ferrell said. Tennessee's Correction Commissioner Frank Strada resigned following the incident, and the governor ordered an independent review.
