HOT SPRINGS  — The Arkansas Board of Corrections is backing a push to move from a three-drug cocktail to a single drug in lethal injections.

Department of Correction spokeswoman Shea Wilson says the board voted Friday to back the attorney general's office going forward with legislation that would involve a single-drug protocol in executions.

Attorney General Dustin McDaniel's spokesman Aaron Sadler says legislation could be filed in the next week or two.

The move comes after the Arkansas Supreme Court last year threw out the state's lethal injection law, siding with death row inmates who said it violated part of the state's constitution that deals with separating the branches of government.

Wilson says the board hopes that narrowing the drug protocol will take care of the court's concerns.
