Watch: The many questions raised by the failed execution of Christa Pike

Tennessee death‑sentenced inmate Christa Pike was taken to a hospital after her heart stopped beating following two lethal injections during her execution attempt, her lawyer said. Her legal team filed an emergency motion to halt the execution as it was underway, stating: "Ms Pike has lost consciousness and still has a heartbeat and is audibly snoring." One of her attorneys told the BBC that Pike, 50, was "being provided life-saving measures" in the hospital after two syringes of pentobarbital had been administered on Wednesday. Pike was sentenced to death in 1996 for the murder of 19‑year‑old Colleen Slemmer. For more on Christa Pike’s story, see https://www.bbc.co.uk/news/articles/cq8r6rjdvlx6o.
