ANDERSON, S.C. — A 14-year-old South Carolina boy was charged as a juvenile Friday with murder and three counts of attempted murder after authorities say he killed his father and opened fire on students at a school playground, wounding three people.The boy did not show any emotion as he walked into the courtroom wearing a yellow jumpsuit. He was unrestrained, not wearing handcuffs or leg shackles, as required by state law in most juvenile cases.As the hearing unfolded, one of the wounded students, 6-year-old Jacob Hall, was on life support and fighting for his life at a hospital about 30 miles away. His family said they were praying for a miracle.Inside the courtroom, the boy's lawyer, Frank Epps, noted that the teen has given a statement to law enforcement and asked that investigators not question him again without his lawyer present.
