Florida 14-year-old boy Knox MacEwen dies while running a 5K race in Florida

A 14-year-old boy died over the weekend while running a 5K race at a Florida high school.

The teen, identified by his family as Knox MacEwen, apparently went into cardiac arrest during the run at Everglades High School Saturday morning, Miramar police told NBC6-South Florida.

Emergency personnel got to the high school at about 9 a.m. and rushed MacEwen to Memorial Miramar, but he couldn’t be saved.

He was later pronounced dead in the hospital, according to the outlet.

The boy was a student at Western High School in Davie and was running for a JROTC (Junior Reserve Officers’ Training Corps) exercise.

The high school principal announced his death to the school community and said grief counselors would be available for students on campus throughout the week.

“One of our JROTC students passed away this morning after being transported to the hospital. I want to offer my deepest condolences to his family and loved ones, teachers, and classmates as they mourn this great loss,” Western High Principal Jimmy Arrojo said in a message obtained by the local station.

MacEwen’s pastor at Crossway Church in Cooper City said the teen was loved by many, making his death a far-reaching and devastating loss.

“Knox’s dad said to me a couple of days ago, that Knox was the best of us, and I love that phrase because if you knew Knox, that’s who he was, right, this is a teenager who when you think about him, you think of a loving kid, a caring kid, a funny kid,” Pastor Jon Elswick said.

A friend of the family launched a GoFundMe that raised more than $66,000 which will be donated to the family to help with funeral expenses and allow the child’s parents to take time off to grieve.

The GoFundMe description also tragically notes that the teen’s mother, Julie, “is still physically and financially recovering from a hard-fought battle with cancer this last year.”
