California's Taft High School was closed Friday as investigators continue to piece together the suspected gunman's motive.
16-year-old Bowe Cleveland was critically wounded in the shooting.
A source close to Cleveland said overnight that the teen is out of surgery and in a medically-induced coma but in stable condition.
Kern County Sheriff Donny Youngblood would not identify the shooter but students say the suspected gunman is 16-year-old Bryan Oliver, a student at the school. Investigators say he walked into his first period science class armed with a 12-gauge shotgun. Authorities say he then took aim at another student but missed.
Teacher Ryan Heber and campus supervisor Kim Fields convinced the gunman to put his weapon down.
The gunman told officials he had been bullied and said he knew his intended victims and had run-ins with them before. Parents told us the gunman was caught last year with a hit list.
"I can tell you that we are investigating that angle and there is probably a likelihood that something like that occurred. We've heard it from several different people we are still interrogating the suspect," said Sheriff Youngblood.
