FLORENCE, Ariz. -- An Arizona prison inmate was executed Wednesday for the 1991 murders of two 13-year-old girls.
Richard Stokley, 60, was convicted of killing Mandy Meyers and Mary Snyder in a ghost town in rural Cochise County. His is the sixth execution in Arizona this year.
Stokley had no formal last words but earlier expressed regret while speaking with members of the execution team during the lengthy setup time.
After the execution, the sister of victim Mary Snyder said she resented Stokley and lamented that her young sister had been killed.
U.S. Supreme Court rulings cleared the way for the lethal injection.
In his final appeals, Stokley's lawyers said he was entitled to a new hearing on sentencing evidence. They also said his constitutional rights were violated because the other man convicted in the case is free after serving 20 years in prison.
