Officials have named the replacement for the doctor who resigned last week after signing off on the lethal injection plan for Nevada’s first execution in over a decade. Jordan Smith, of the state attorney general’s office, told a judge Monday in Las Vegas that Dr. Leon Ravin has replaced Dr. John DiMuro as the state’s top doctor. That makes Ravin the medical official with primary responsibility for next week’s scheduled execution of twice-convicted murderer Scott Dozier. Dozier wants his sentence carried out. But he’s letting federal public defenders challenge the state plan to use a never-before-tried combination of drugs for his scheduled November 14 execution at Ely State Prison.
