REVEALED: Cause of death for female air force cadet, 19, mysteriously found dead in her dorm room

The cause of death of the 19-year-old air force cadet who was mysteriously found dead in her student room has been revealed.

Avery Koonce, 19, of Texas, was found unresponsive at the Colorado Springs Air Force Academy on September 4.

Despite emergency responders attempting life-saving measures, Koonce was pronounced dead at the scene.

But after a month-long investigation, the El Paso County coroner’s office was able to determine the cause of her death.

According to the autopsy report, Koonce died from a relatively rare but potentially fatal anaerobic bacteria called Paeniclostridium sordellii.

The bacteria caused sepsis in her lungs and worsened an existing respiratory infection, leading to her death.

Paeniclostridium sordellii is associated with a toxic shock syndrome that can rapidly lead to death. It was found in both her blood and lungs.

The report also stated that Koonce’s left lung showed “histological evidence of acute inflammation.” Days before her death, she had been struggling with a severe cough.

In other rare cases, the bacteria can also cause pneumonia, endocarditis, arthritis, peritonitis and myonecrosis, with a mortality rate of more than 70 percent.

According to the Centers for Disease Controlis the source of the deadly bacteria ‘probably the vagina, which is known to be colonized with Clostridium species in some females’.

The track star’s death was ruled ‘natural’ after her cause of death was discovered.

In a heartbreaking statement after Koonce’s death, her parents Eric and Kelly described their daughter as “an incredibly bright light in this broken world.”

Her obituary read: “Avery was much loved. Avery, in turn, loved life and others deeply. She lived passionately and was a friend to everyone she met.

“Avery had a way of connecting with people, and she had a smile that would brighten anyone’s day. You only had to know Avery for a few minutes to make a lasting impression on you.’

Koonce was a 2024 graduate of Thrall High School in Taylor, Texas, and enrolled in the Air Force Academy shortly after graduating, reports CBS News.
