A death row inmate in Tennessee appeared to defy death after his execution, with an electrocardiogram showing that his heart continued to beat for nearly two minutes post-official time of death. Byron Black, 63, was found guilty of murdering his girlfriend and her two young daughters in 1988. His lawyer claims the EKG showed “sustained cardiac activity” during the execution, sparking controversy over the state’s lethal injection protocol. The case is part of an ongoing lawsuit claiming that the protocol infringes upon constitutional prohibitions against cruel and unusual punishment.
