(CNN) — A team of medical examiners has ruled that Oklahoma death row prisoner Clayton Lockett died from the state’s lethal injection and not by heart attack.The report, which was released Thursday by the Oklahoma Department of Corrections, called the manner of death a “judicially ordered execution.”

The controversial April 29 execution of Lockett, who was convicted in 1999 of murder and rape, took 43 minutes from the time he was first injected.

Witnesses described the man convulsing and writhing on the gurney, as well as struggling to speak, before officials blocked the witnesses’ view. The execution was halted, but Lockett eventually died.
