Nevada prison authorities want to begin using a never-before-tried combination of drugs, including fentanyl, ketamine, and potassium chloride, for the state’s first lethal injection in 15 years, reports NPR. A possible late-July death date for convicted mass killer Zane Michael Floyd might also substitute alfentanil, asimilar-acting drug, for fentanyl and potassium acetate might substitute for potassium chloride. The muscle paralytic cisatracurium would also be used to stop the condemned man’s ability to breathe before he receives the heart-stopping agent.
Floyd, who was sentenced in 2000 for killing four people and wounding a fifth in a shotgun attack at a Las Vegas grocery store in 1999, does not want to die, but has lost state and federal appeals and the U.S. Supreme Court declined to hear his case. And while U.S. District Judge Richard Boulware II said he may issue a stay of execution by the end of the month to allow time to review the choice of drugs and a 65-page Execution Manual, A state judge in Las Vegas said this week that prosecutors and prison officials can begin planning his execution for the week of July 26.
