2 death row inmates seek execution by firing squad instead of lethal injection method: 'It will be quicker'

• Two Oklahoma death row inmates have opted for executions by firing squad over lethal injection.
• The state recently resumed executions following several botched lethal injections in 2014 and 2015.

Two Oklahoma death row inmates with impending executions have requested death by firing squad instead of by lethal injection, according to Monday court documents obtained by Insider.

Inmates Donald Grant and Gilbert Postelle have asked a judge to allow a temporary injunction to halt their executions until a trial — scheduled to begin on February 28 — comes to a conclusion about the constitutionality of the three-drug lethal injection protocol.

In the meantime, Grant — whose execution was scheduled for January 27 — and Postelle — whose execution is scheduled for February 17 — were required to choose an alternative execution method: They chose death by firing squad.

"While it may be gruesome to look at, we all agree it will be quicker," attorney Jim Stronski told US District Judge Stephen Friot Monday following a hearing, according to The Associated Press.

Grant was convicted for killing two hotel employees during a robbery in 2001. His public defender requested mercy for Grant, claiming that he was suffering mental illness and brain damage — but the request was denied, according to The Oklahoman.

Postelle was convicted at 19-years-old for killing two people alongside his father and brother in 2005. His attorney said that he was under the influence of his father and methamphetamine. She added that he has become a changed man since his arrest, according to The Associated Press.

The 'Sooner State' resumed executions in October of last year after a six-year hiatus following botched executions in 2014 and 2015.

Witnesses say that John Marion Grant convulsed and vomited during the 15 minutes after the lethal injections. He was declared dead six minutes later.

Oklahoma Department of Corrections declined to comment. Attorney Jim Stronski did not immediately respond to Insider's request for comment.
