TULSA - The Oklahoma Department of Public Safety released the autopsy report on Clayton Lockett, the man whose execution went terribly wrong earlier this year.
The cause of death is listed as "the result of judicial execution by lethal injection."
It found that there were seven attempts to start an IV line on Lockett, a process which took some 45 minutes.
The Oklahoma Department of Corrections had said that Lockett died of a heart attack after his execution was officially halted.
The report also indicates that the IV was started by a phlebotomist, not a paramedic, as stated by the DOC.
During the process, the prisoner's femoral vein was perforated, according to the report, which goes on to say that his veins had "excellent integrity" for the placement of an IV.
It lists the execution protocol medications as midazolam, vecuronium and potassium chloride.
Previously, the state has refused to name the drugs used.
It's also facing a lawsuit by news agencies protesting that their First Amendment rights were violated when prison officials drew a curtain, blocking a view of the execution after it began to go wrong.
