(CNN) -- [Breaking news update, 4:09 p.m. ET}
The dead gunman was a male student at the high school, Sheriff Grayson Robinson told reporters. He declined to identify the student.
"We have not been able to locate a second suspect, but that's part of our ongoing investigation," the sheriff said.
The shooting began after the student entered the school and identified a teacher whom he wanted to confront, Robinson said. That teacher was informed of the situation and exited, he added. One student was taken to a hospital in serious condition with a gunshot wound; another was injured, though the cause was not clear, he said.
