OKLAHOMA CITY – On Thursday, the Oklahoma Department of Public Safety announced that it has received one of the final pieces of evidence necessary to complete its investigation into the death of an Oklahoma inmate following a botched execution.
On April 29, Clayton Lockett was scheduled to die by lethal injection.
After being injected with a lethal injection drug cocktail, witnesses say Lockett was conscious, moving and talking throughout the process when he should have been unconscious.
After nearly 45 minutes, Lockett was pronounced dead after prison officials say he suffered a massive heart attack.
An independent autopsy, which was ordered by Lockett’s attorneys, claimed he died because the IV was improperly placed in his vein.
It stated the injection drugs were absorbed into his muscle, causing a painful and drawn out execution.
Gov. Mary Fallin ordered an independent autopsy be performed in Dallas, so an unbiased party could determine exactly what happened during the execution.
On Thursday, the Southwestern Institute of Forensic Science at Dallas released the medical examiner’s autopsy report on Clayton Lockett.
The autopsy report says there were numerous puncture marks all over Lockett’s body, including three or four puncture marks of the right jugular region, meaning there was trouble finding a viable vein to start an IV during the execution.
It states that Lockett had “cardiac hypertrophy” and “myxomatous degeneration,” but officials did not conclude that he died from a heart attack like prison officials claimed.
In its conclusion, it states that Clayton Derrell Lockett “died as a result of judicial execution by lethal injection.”
Reports state that Lockett was given all of the execution drugs in his groin.
It also states that Lockett “regained consciousness and began convulsing’ upon the injection of vecuronium bromide, however there are conflicting statements on the deed’s level of consciousness and the amount of movement he was exhibiting.”
