WASHINGTON, D.C.: The state of Virginia late Thursday executed multiple murderer Alfredo Prieto, rejecting last minute court appeals from lawyers for the Salvadoran immigrant. Prison officials said in a statement that Prieto, who was put to death by lethal injection, was pronounced dead at 9:17 pm (0117 GMT Friday). His final words, they said, were: “Let’s get this over with.” Prieto had been convicted of or linked to nine killings across the United States. His attorneys had filed a lawsuit seeking to temporarily postpone the execution over objections to the mix of drugs used in the lethal injection, but a federal judge rejected their appeal. Prieto’s execution was the third scheduled in the United States this week, just two of which were actually carried out. The United States remains the only Western country to maintain the death penalty and has carried out 21 executions so far this year.
