Arkansas Department of Correction spokesman Solomon Graves said the state has 100 vials of potassium chloride, one of three drugs used in the state's lethal injection protocol. He did not say who provided the state with its new supply, citing an Arkansas law that keeps the source of its lethal injection drugs secret. Hutchinson scheduled the executions days after the U.S. Supreme Court said it wouldn't review a state court ruling upholding Arkansas' lethal injection law. Attorneys for the inmates have asked a Pulaski County circuit judge to find the state's lethal injection law and the three-drug protocol unconstitutional. Arkansas has had multiple executions in the past, including triple executions in 1994 and 1997.
