School isn't even in session yet and already Canyon High School in Anaheim is dealing with a tragedy.
14-year-old Mitchell Cook, an incoming freshman, suddenly collapsed Wednesday during football practice and later died at the hospital.
"He collapsed and the coaches immediately go the trainer over there and immediately called 911," said Tommy Crammer, one of Mitchell's teammates.
School staff gave Mitchell CPR and paramedics got there quickly, but they couldn't save him.
"I was just so shocked that it happened. He was so young and that's just not supposed to happen," said Kyle Dubau, another player.
In these photos that now decorate a school fence, you can see Mitchell with friends having fun. Now, those friends and his team mates are left wondering what happened?
"They were just beginning warm ups. It was nothing, no running around yet. It wasn't even that hot," said Tommy.
The entire football was on the football fields practicing when Mitchell became ill, including Mitchell's brother who also plays football, "He rushed up there as fast as he and he was with him when it happened and throughout the night," said Tommy.
An autopsy will determine if Mitchel had any pre-existing health issues.
Thursday evening the school had a meeting for players and their families.
A candle light vigil is planned at Canyon High
School on Saturday at 7pm.
