SCOTUS To Hear Death Penalty Challenge:  The U.S. Supreme Court has agreed to review the death penalty case of McKinney v. Arizona next term.  Jordan s. Ruban of Bloomberg Law reports that attorneys representing double-murderer Erin McKinney believe that because his 1993 sentencing did not comply with the Supreme Court's 2002 decision in Ring v. Arizona and that the sentencing jury did not consider McKinney's abusive childhood, he is entitled to be resentenced.  In March 1991, McKinney and his half-brother burglarized the home of Christine Mertens.  During the burglary McKinney beat Mertens, stabbed her several times then held her face down on the floor while shooting her in the back of the head.  Two weeks later the brothers burglarized the home of Jim McCain, shooting him in the back of the head while he slept in his bed.
