Court filing describes repeated IV problems during Tennessee's Christa Pike execution attempt

Tennessee execution staff made repeated attempts to place IV lines during Christa Pike's September execution attempt, according to a court filing by her attorney reported by PBS NewsHour and ABC News. The filing says staff warned that a vein may have ruptured before lethal drugs were administered.

Pike survived two doses of pentobarbital and was hospitalized. The allegations were filed in separate litigation challenging Tennessee's lethal-injection procedures.
