The first woman in 70 years was executed in the southern US state of Georgia early on Wednesday for her role in the killing of her husband, US media reports said.
Kelly Gissendaner’s execution by lethal injection was delayed from Tuesday night after her attorneys filed last-minute appeals, all of which failed.
A letter written by Pope Francis, who had called for a global abolition of the death penalty last week during a visit to the United States, also failed to sway the Georgia Board of Pardons and Parole into granting Gissendaner, 47, clemency.
Gissendaner, a mother of three, was convicted of murder for persuading her boyfriend to kill her husband, Douglas Gissendaner, in a 1997 stabbing. Her accomplice, Gregory Owen, received a sentence of life in prison.
