Cadet Avery Koonce Passes Away
Avery Koonce, 19, of Tyler, Texas, tragically died on September 4th in her Colorado dorm room at the U.S. Air Force Academy. According to an autopsy by the El Paso County Coroner’s Office, her death resulted from complications of a severe lung infection. Experts suggest that timely medical care could have prevented this loss.
Rare Bacterial Infection Linked to Pneumonia
The autopsy report listed Koonce’s cause of death as “paeniclostridium sordelli sepsis complicating parainfluenza laryngotracheobronchitis”. This rare bacterial infection followed a viral lung infection.
Renowned forensic pathologist Dr. Michael Baden, who reviewed the findings, explained, “In essence, she died of untreated pneumonia.” He noted that while the bacteria is rare and linked to severe toxic shock-like syndromes, the viral infection likely weakened her immune system. Dr. Baden added that her condition could have been treated with antibiotics and fluids.
Symptoms Often Overlooked
Before her death, Koonce likely experienced typical pneumonia symptoms, including persistent coughing, fever, and difficulty breathing. The autopsy revealed she had struggled with a chronic cough, which worsened in the days before her death.
Dr. Baden emphasized that many people underestimate their symptoms until it’s too late. This may explain why Koonce did not seek care in time.
