Avery Koonce was a young woman whose speed on the track matched the brightness of her spirit. A record-setting sprinter in the 100- and 200-meter dashes at her Texas high school,

she brought that same passion and determination with her to the United States Air Force Academy, where she had just begun her freshman year and joined the women’s

track and field team. At only 19, Avery’s life was just unfolding—full of plans, potential, and purpose.

On September 4, 2024, that promising journey came to a sudden, heartbreaking halt. Emergency responders arrived at Avery’s dorm room at the Air Force Academy in Colorado Springs to find her unresponsive.

Despite every effort to revive her, she was pronounced dead at the scene. Her fellow cadets had found her unconscious, setting off a flurry of shock, grief, and questions.

The autopsy conducted by the El Paso County Coroner’s Office later revealed the cause of death as Paeniclostridium sordellii sepsis, which developed as a

complication of viral pneumonia. More specifically, the condition was described as “Paeniclostridium sordellii sepsis complicating parainfluenza

,” a severe bacterial infection triggered by a prior viral illness in her respiratory tract.

This rare and aggressive bacteria is known to cause a toxic shock-like syndrome, and in Avery’s case, it overwhelmed her immune system at a time when she was already vulnerable from a lower respiratory infection. It was reported that she had been dealing with a bad cough in the days before her death. A forensic pathologist, Dr. Michael Baden, shared with IBT that earlier detection and antibiotic treatment might have saved her life—pointing to the painful possibility that her passing was preventable.

The bacteria had spread into her bloodstream and lungs. In medical terms, it was sepsis. In human terms, it was a stunning and tragic loss of someone who was just beginning to chase her dreams.

Avery had recently graduated from Thrall High School in Texas, where she was more than just a standout athlete. She was a cheerleader, a powerlifter, a cross country runner, a band member, and a top student. At the academy, she was planning to major in biology and minor in kinesiology, with hopes of becoming a physical therapist for Air Force pilots. Her drive to serve others never wavered.

On September 12, a memorial was held at Tiger Stadium in her hometown of Thrall. In a powerful show of solidarity and remembrance, around 100 of Avery’s classmates from the Air Force Academy traveled from Colorado to Texas to honor her memory. Lt. Gen. Tony Bauernfeind, Superintendent of the Academy, said, “We lost an incredible teammate,” emphasizing Avery’s impact on her peers, squadron, and athletic team during her brief time at the academy.

Avery’s family, heartbroken but full of love, released a statement through the Academy that captured the essence of who she was: “Our daughter, Cadet Avery Koonce, was an incredibly bright light in this broken world. Our lives will forever be diminished because of her absence… Avery was not a perfect person but was a perfect daughter.”

They also shared a glimpse into their grief and their faith: “Loving on her brothers and learning how to live with Avery’s loss is our only focus right now. We are beyond blessed for the 19 amazing years we got to call Avery ours.”

Those who knew Avery will remember not just her achievements, but her heart. Her energy, her smile, her kindness—all of it left a mark. She lived with purpose, and in that short time, she inspired others to push harder, run faster, and love more deeply. Her story, though heartbreaking, is also a tribute to a life lived with vibrant intention.
