Timeline of events involving capital punishment in Oklahoma

OKLAHOMA CITY (AP) — Oklahoma conducted 112 executions from 1976 to October 2015, when the state imposed a moratorium following three consecutive flawed executions or attempted executions. That number rose to 113 on Thursday with the execution of John Marion Grant. It was the state’s first execution in more than six years.

The 2014 lethal injection of Clayton Lockett was the first of three problematic executions that led to a moratorium in Oklahoma, which has historically had one of the nation’s busiest death chambers. Lockett’s botched execution let him struggle on a gurney before dying 43 minutes into his lethal injection.
