14-Year-Old Boy Dies After Suffering Cardiac Arrest While Running 5K

A 14-year-old boy has died after suffering cardiac arrest while running a 5K at a Florida high school on November 4, 2023. According to a police statement, Knox MacEwen had collapsed and was found experiencing cardiac arrest when authorities arrived at the Junior Reserve Officers’ Training Corps (JROTC) 5K at Everglades High School in Miramar, Florida. After transporting the teen to Memorial Miramar Hospital, he was pronounced dead by doctors. A GoFundMe has been created to support the family.

MacEwen was a part of the JROTC program at Western High School in Davie, Florida. He volunteered at his church in the kids’ ministry. His mother recently had cancer and the family is still managing the lingering physical and financial effects of her illness, according to the GoFundMe.

"The family has been through the unimaginable,” it read. The funds raised will “allow Knox’s parents, Kevin and Julie, to take time off work to grieve.”
