The Oklahoma Department of Corrections has issued a statement about the development of a new protocol for the state's death penalty.

Executions are set to resume in Oklahoma following a three-year hiatus following the discovery of a "pharmaceutical mistake" in the case of death row inmate Richard Glossip.

Recent high-profile court cases have put the death penalty in Oklahoma back in the spotlight. 

The scheduled executions of Oklahoma’s some 50 Death Row inmates have been on hold for close to two years after the bungled near-execution of Richard Glossip in September 2015.

One day after the nation's first successful double execution in 17 years, Oklahoma officials are scheduled to release their death penalty review, almost two years after the state put a hold on executions.

It's been more than a year and a half since executions in Oklahoma were halted - forced by the discovery of a pharmaceutical mistake in the high-profile case of Richard Glossip. 

Justin Dougherty sat down with Richard Glossip’s defense attorney to talk about the case and the upcoming Discovery ID docu-series, “Killing Richard Glossip.” Episodes will air April 17 and 18.

Tucked inside last week's scathing Multicounty Grand Jury report was a recommendation the state begin moving away from lethal injection. Instead jurors suggested the state hire experts to take a look at moving to nitrogen hypoxia; a suggestion that renewed arguments over the feasibility, legality and moral efficacy of Oklahoma’s back-up execution method.

The calls started around 12:30 p.m. on Sept. 30, 2015, three hours before convicted murderer Richard Glossip's third scheduled execution. 

A special grand jury investigating three botched execution attempts in Oklahoma has delivered a 106-page report to a judge.
