Two Oklahoma death row inmates choose firing squad to delay execution

Donald Grant and Gilbert Postelle seek to delay executions until trial is held on whether lethal injection method is constitutional

Two men on Oklahoma's death row - at the prodding of a federal judge - agreed to choose execution by firing squad as a way to delay their upcoming lethal injections, one of their attorneys told the judge.

The two inmates, Donald Grant and Gilbert Postelle, want US district judge Stephen Friot to grant them a temporary injunction that would halt their upcoming executions until a trial can be held over whether Oklahoma's three-drug lethal injection method is constitutional.
