This news from Oklahoma: A 22-year-old man who asked a court to schedule his execution was killed by injection early today, the youngest person to be put to death since capital punishment was reinstated in 1976. Scott Dawn Carpenter, who pleaded no contest to stabbing a store clerk to death, apologized in a letter to the victim’s family and left a statement. He said, “I tell the young and old, do not stray onto the wrong path in life as I did. I speak from experience when I say it’s a long and bumpy road, with a lot of regret and few second chances.”
