11-year-old dies after collapsing during track practice at Miami Northwestern Senior

An 11-year-old boy died after collapsing Wednesday as he warmed up for track practice at Miami Northwestern Senior High School, according to Miami-Dade County Public Schools Superintendent Alberto Carvalho.

“No deeper pain than suffering loss of one's child,” he tweeted. “Tonight, we mourn alongside the family of a boy who passed away following track practice.”

Miami police, who is investigating the incident, would not confirm on Wednesday night whether the boy had died.

The boy is part of a track club that meets at the school, 1100 NW 71st St.

Miami Fire Rescue Capt. Ignatius Carroll said the boy was warming up when several people saw him collapse.

“Several people could hear the kids telling him to get up,” Carroll said. “That’s when the adults went over and realized something was wrong.”

Miami Fire Rescue responded and found the boy was not breathing and began CPR. He was taken to Jackson Memorial Hospital’s pediatric unit in extremely critical condition, Carroll said.

It was not immediately known what cause the boy to collapse, Carroll said.
