A 15-year-old boy collapsed and died during a physical education class at Centennial High School.
Caleb Hannink died at 2:28 p.m. Thursday, according to the Kern County Coroner's Office.
The school called an ambulance immediately and it arrived within five minutes, but the boy died after he was taken to Bakersfield Heart Hospital, according to Kern High School District spokesman John Teves.
Grief counselors were on campus Friday, he said.
"He was a good kid," Teves said. "He was well-liked. They're having a tough time. We're trying to help them the best we can."
