Columbia, Apr 15 (AP) A South Carolina prisoner scheduled to be the first man executed in the state in more than a decade has decided to die by firing squad rather than in the electric chair later this month, according to court documents filed Friday.

Richard Bernard Moore, 57, is the also first state prisoner to face the choice of execution methods after a law went into effect last year making electrocution the default and giving inmates the option to face three prison workers with rifles instead.

Moore has spent more than two decades on death row after being convicted of the 1999 killing of convenience store clerk James Mahoney in Spartanburg. If executed as scheduled on April 29, he would be the first person put to death in the state since 2011.

The new law was prompted by the decadelong break, which corrections officials attribute to an inability to procure the drugs needed to carry out lethal injections.

Moore's attorneys have asked the state Supreme Court to delay his death while another court determines if either available method is cruel and unusual punishment. The attorneys argue prisons officials aren't trying hard enough to get the lethal injection drugs, instead forcing prisoners to choose between two more barbaric methods.

His lawyers are also asking the state Supreme Court to delay the execution so the U.S. Supreme Court can review whether Moore's death sentence was a disproportionate punishment compared with similar crimes. The state justices denied a similar appeal last week. (AP)
