Attorney General Doug Peterson said this Thursday that he is prepared to request a death warrant for Jose Sandoval. However experts say that the new four-drug combination that officials unveiled has never been used in another state for an execution before. The four drugs include diazepam, fentanyl citrate, cisatracurium besylate, and potassium chloride. Robert Dunham, director of the Death Penalty Information Center, said that none of these drugs had been used together by another death penalty state. “It’s yet another experimental protocol. Now the lawsuits begin” said Dunham. State Senator Ernie Chambers, the leading opponent of capital punishment in the state, said the new and untested protocol would inspire lengthy legal action.
