Clayton Lockett execution (2014)
Clayton Lockett, 38, was given a three-drug lethal injection in Oklahoma. After the sedative midazolam, he writhed on the gurney and spoke before being declared unconscious; he died of a heart attack roughly 43 minutes after the procedure began.
Oklahoma suspended executions and a national review of injection protocols followed. The Supreme Court upheld Oklahoma's method in Glossip v. Gross (2015) but confirmed that inmates may challenge execution methods.
Lockett's death became the reference point for lethal-injection litigation, including Pike's claim that Tennessee's procedure risks unconstitutional suffering.
A botched injection launched a decade of method challenges. Pike's two failed doses could do the same, and her survival keeps her challenge alive.
