FLORENCE, Ariz. (AP) — An inmate was executed Wednesday after being convicted of murdering two 13-year-old girls in a ghost town where they were raped, strangled and stabbed before being dumped in a partly flooded mine shaft.

Richard Dale Stokley, 60, was put to death at a prison in Florence two decades after he and another man were convicted of murdering Mandy Meyers and Mary Snyder in 1991 in rural Cochise County.
