Controversy continues over Arkansas's rush to conduct four double executions in four days this month.
One issue raising concern is the use of the common sedative midazolam, marketed under the trade name Versed. The drug has been tied to botched executions where inmates wake up during the procedure. Some states have stopped using it altogether for lethal injections.
KUAR News spoke with Sean Murphy in Oklahoma, who covers executions for the Associated Press. He witnessed the highly-publicized botched execution of Clayton Lockett in 2014.
