TULSA, Oklahoma - New details are emerging about the moments leading up to the execution of Clayton Lockett.

News On 6 reporter Tess Maune was the only Tulsa TV reporter who witnessed the execution and from where she was sitting, it looked like those IVs went down along his arms, then disappeared beneath a sheet, but a report released Thursday said they administered the drugs through his groin.

Lockett was a cold-blooded killer. He shot 19-year-old Stephanie Neiman twice with a shotgun, then ordered an accomplice to bury her alive, as she cried out from the shallow grave.

Court documents say Lockett never showed remorse. They also reveal Lockett was a menace behind prison walls, just as he was as a free man.

He was caught with handmade knives. He was aggressive, disrespectful and repeatedly threatened correctional officers; traits that followed him to his dying day.

A state report shows the morning of his execution Lockett had to be Tasered because he refused to be restrained for a mandatory x-ray. He also cut his own arm, but didn't need stitches.

The inmate refused to eat because his final meal request had been denied; he wanted an elaborate surf and turf dinner that exceed the $15 limit.

Once Lockett was in the execution chamber, it took the doctor an hour to find a viable vein for the IV. Lockett's arms, legs, feet and neck couldn't be used, so the IV was inserted in his groin area.

The doctor discovered Lockett's vein had collapsed 33 minutes after the drugs were administered. The doctor said the drugs had either absorbed into tissue, leaked out or both.

At that point, Lockett hadn't been given enough drugs to kill him and the execution was stopped. Ten minutes later, Lockett died of an apparent heart attack.

Now, Oklahoma's execution policy is under review, The Department of Corrections Director wants to rewrite the rules for state executions, and until those revisions are approved, no one will be put to death in Oklahoma.

Twice on his execution day, Lockett refused to see his attorneys, the same attorneys who fought to have the state study Oklahoma's new drug cocktail before it was used in an execution.

His attorneys were seated on the front row to watch the execution.
