"He went to bed, no problems. He woke up, no problems - being his goofy self," Peyton's father Corey told Fox29.
Just 15 minutes before he collapsed, Mr West took a photo of the teenager smiling with his school back pack as he headed off to school.
Classmates and teachers gathered at the school's football field to remember the teenager.
