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. The state's previous supply of the drug had expired in January.
"Coupled with the two remaining drugs, there are enough to carry out the scheduled executions," he said.
Graves said the latest supply of the drug was received March 8 and expires at the end of August 2018. 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. Graves also did not say how much the potassium chloride cost and declined to release redacted photos of the drugs' labels, which The Associated Press had previously used to identify the source of another Arkansas execution drug.
The state hasn't executed an inmate since 2005, but Gov. Asa Hutchinson last month scheduled the eight executions to occur before another drug, midazolam, expires at the end of April.
