The State of Arkansas has executed four inmates in just eight days, after choosing to rush the executions in advance of the April expiration of one of the sedatives.

The last person to be executed was 38 year old, Kenneth Williams. Williams died by lethal injection at 11:05 p.m. at the Cummins Unit prison in Varner, Arkansas. Williams is one of the eight inmates who had been scheduled for the death penalty before Arkansas’s supply of sedatives used in its lethal injections expires at month’s end.

Williams was sentenced to life in prison for the 1998 killing of Dominique Hurd, a university cheerleader.

He was later convicted of capital murder after he escaped from prison in 1999 and killed Cecil Boren, the owner of pickup truck that Williams stole and was, later, captured driving.

Boren’s daughter, Jodie Efird, watched Thursday night’s execution from the death chamber in Arkansas’ Cummins Unit prison. She said Williams’s death may not bring closure to her family, but it helps a little.

“Every time we drive down this road, he’s not here anymore,” she said of Williams.

Williams chose to make a final statement before the administration of the drugs.  “I was more than wrong. The crime I perpetrated against you all was senseless,”

Arkansas Governor, Asa Hutchinson, had put a temporary hold on Williams’ execution Thursday evening to allow the US Supreme Court to consider motions for stays of execution. The court denied all the motions.

The expiration is an issue because a resupply is uncertain as Arkansas and other states struggle with suppliers that don’t want their products used in executions. The sedative midazolam is a controversial replacement for anesthetics that Arkansas and other states can no longer obtain.
