While it has been more than five years since an execution has taken place in Oklahoma, execution dates have been set for several death row inmates.
These will be the first executions performed in Oklahoma since 2015.
In 2014, the State of Oklahoma executed Clayton Lockett for killing 19-year-old Stephanie Nieman in 1999.
The resulting 43-minute procedure featured a never-before-used combination of execution drugs and went awry as Lockett awoke from his unconscious state, and began twitching and convulsing on the table.
“The doctor checked the IV and reported the blood vein had collapsed, and the drugs had either absorbed into tissue, leaked out or both,” according to a previously released timeline.
Lockett died of a heart attack 43 minutes after the execution began.
