Horry County police have set up a series of security checkpoints at Socastee High School Wednesday morning, following yesterday's shooting.
School will start on a one hour delay because of the amount of time that will be needed for students to get into the school and through the heightened security.
Horry County schools have set up metal detectors at the entrance to the school, and each student will be searched before entering the building.
The student, a 9th grader, remains in custody. His name is not being released because of his age. Police have not said what charges he faces.
