Stacey Torrance was in his prison cell Monday, writing to his attorney for an update, when the news he sought came blaring out of his TV: The U.S. Supreme Court had declared mandatory life-without-parole sentences unconstitutional for juveniles."I waited another 15 or 20 minutes to hear them say it again, because I wanted to make sure my eyes saw it right," said Torrance, an inmate at the state prison in Chester, who was 14 when he helped plan a robbery that ended with the kidnapping and murder of a West Philadelphia teenager in 1988.
