FLORENCE, Arizona — Prison officials in Arizona are preparing to execute a 47-year-old man for a double-murder during a Phoenix convenience store robbery that netted $72.
Eric John King is set to die by lethal injection at 10 a.m. Tuesday at the state prison in Florence. He is one of the last Arizona death-row inmates to be killed with a three-drug cocktail after state officials said last week they will switch to a single-drug method.
King was convicted of shooting and killing security guard Richard Butts and convenience store clerk Ron Barman two days after Christmas in 1989.
King has maintained his innocence since his arrest, and lawyers are still fighting to delay his execution. They question the state's execution procedures and say there is "substantial doubt" about King's guilt.
