Lawyers for Christopher Pittman wanted the justices to examine whether the long prison term for a child violates the Constitution's ban on cruel and unusual punishment. With no possibility of parole, he will be 42 before he is released, they said.
Pittman is the only inmate serving such a lengthy sentence for a crime committed at such a young age, his lawyers said. The judge who sentenced him was prohibited by law from taking his age into account.
South Carolina contended the punishment is proportionate to the crime and said there is a national trend of increased punishment for young violent criminals.
Pittman used a shotgun to shoot Joe and Joy Pittman in their bed and then set fire to their home in 2001. During his trial four years later, Pittman's attorneys unsuccessfully argued the slayings were influenced by the antidepressant Zoloft — a charge the maker of the drug vigorously denied.
