ANAHEIM, Calif. (KTLA) — A candlelight vigil was held Saturday in Anaheim for a 14-year-old boy who died after collapsing during football practice.

Mitchell Cook, a student athlete at Canyon High School, collapsed Wednesday while practicing with the school’s freshman football team. Coaches and the school’s athletic trainer performed CPR until paramedics arrived.

Mitchell was pronounced dead Wednesday evening after he was taken to two hospitals.

“He just was always happy and just laughed with everybody,” his friend Ethan Rogers said.

The vigil was held at the school’s football field, where a makeshift memorial was created.

Flowers, pictures and football helmets were placed there to honor Mitchell, who had a known heart condition but was seeing doctors regularly to monitor it. He was apparently doing well shortly before he died.

He had been preparing for his first year of high school and his first game as a Comanche, the school’s mascot.

“He was like a little brother that I never had,” another friend of Mitchell’s, Kenny Cho, said. “I love him to death. He’ll watch over us and we’ll play with him at our games.”
