April 30 - Oklahoma inmate died during a botched execution, minutes after a doctor had called a halt to the procedure, raising more questions about new death penalty cocktails. Sarah Toms reports.
Inside this Oklahoma prison a death row inmate died of a heart attack during a botched execution. Clayton Lockett, who was only 38 years-old, experienced a vein failure which prevented the lethal injection of three drugs from being fully effective. The execution was halted when it became obvious something had gone wrong and penetentiary workers blocked the view of the guerney. (SOUNDBITE) (English) MEDIA WITNESSES, SAYING: "At 6:39 he's still lifting his shoulders and head, off the gurney, grimacing. And appeared to be in distress." (SOUNDBITE) (English) MEDIA WITNESSES, SAYING: "So from 6:23, the execution started. 6:39 is when they closed the curtains on us. A 16-minute process to watch." The failed execution is likely to raise more questions about the lethal injection and whether it is humane. Lockett was sentenced to death here for shooting and eventually killing a woman by burying her alive. The execution of fellow inmate Charles Warner, which was due to take place just two hours later, was postponed for 14 days. The two men had unsuccessfully challenged the state over the cocktail of chemicals used in the lethal injection. Lawyers argued the state was withholding information about the drugs used. But the state says the law is necessary to protect the suppliers from legal action and harassment. US states have had increasing problems trying to obtain drugs used in executions, amid an embargo by European pharmaceutical firms.
