A South Carolina teenager suspected of killing his father and wounding two boys and a teacher at an elementary school has been charged with one count of murder and three counts of attempted murder.
The 14-year-old boy, who has not been named by authorities, will remain in custody for at least another 48 hours after he appeared before a state judge for a hearing behind closed doors on Friday, the Anderson Independent-Mail reported on Friday.
The hearing did not consider the question of whether he will be tried as an adult.
The teenager was arrested on Wednesday after police said he crashed a pickup truck into a fence around Townville Elementary School and then shot and wounded two students and a teacher.
Prior to that, he had shot and killed his father, 47-year-old Jeffrey Osborne, as the man watched television at their home near the school.
The shooting was the latest at a US school to stoke debate about access to guns.
Many schools have bolstered security since 2012 when a gunman shot and killed 20 children and six educators at Sandy Hook Elementary School in Newtown, Connecticut.
Six-year-old Jacob Hall, one of the students who was shot at Townville Elementary, remained in critical condition at a local children's hospital on Friday, a hospital spokeswoman said.
His family said he is on life support after a bullet tore his femoral artery, causing blood loss that led to a "major brain injury".
The teacher, Meghan Hollingsworth, and another boy, also aged six, were less badly hurt.
Authorities said they did not know of any link between the shooter, who was home-schooled, and the victims.
