ORLANDO, Fla. (AP) — A Florida sheriff says a 15-year-old high school student was fatally shot while walking to school.

Orange County Sheriff John Mina said first responders treated the student at the scene on Tuesday morning. He was then taken to a hospital where he was pronounced dead.

Mina asked the public for any information about the shooting. He says so far no witnesses have come forward saying they saw what happened.

Mina says investigators believe the student was walking by himself and that he lives in the neighborhood around Boone High School in Orlando.

The student's name wasn't immediately made public.
