Austin Stallman, a 21-year-old Texas A&M senior and the son of Brazoria County Sheriff Bo Stallman, collapsed during a nine-mile run in College Station last month and died early Tuesday morning after nearly two weeks of fighting multi-organ failure. The run was part of a semester-long tryout for a student organization that prepares Texas A&M students for Navy SEAL training.
A fellow student running beside Stallman flagged down a passing motorist in College Station, who called 911 for emergency help.
Doctors diagnosed him with exertional heatstroke and rhabdomyolysis, a condition that led to critical complications in his kidneys, liver, and blood coagulation system, according to KHOU. Per the station's report, Stallman spent roughly two weeks in intensive care receiving continuous dialysis and transfusions before he died at approximately 4:15 a.m. Tuesday.
Sheriff's Office Announces the Loss
The Brazoria County Sheriff's Office announced Stallman's death early Tuesday, saying the family is heartbroken, according to reporting from Click2Houston. The office thanked the Brazoria County community for its support and encouragement throughout Stallman's hospitalization, writing that “we cannot thank you enough and we will never forget,” and asked residents to continue supporting the family as they grieve.
Bo Stallman is the sheriff of Brazoria County, according to Brazoria County.
Community Rallies With Blood Drives
Local law enforcement agencies organized blood drives across Texas in Stallman's honor while he was hospitalized, including one held by the Manvel Police Department at the Keith Traylor Criminal Justice Facility on September 28, according to the City of Manvel. Additional drives were held at the Brazos Valley Donor Center on September 18 and 19.
How Illness Can Turn a Workout Deadly
Medical guidance from the Mayo Clinic and military health organizations warns that recent viral or febrile illnesses severely impair the body's ability to regulate temperature, significantly raising the risk of exertional heat stroke during intense physical activity, according to the Mayo Clinic. That risk climbs further when someone trains while under-hydrated or still recovering from an infection.
Exertional rhabdomyolysis, the condition Stallman developed, occurs when damaged muscle tissue breaks down and releases proteins like myoglobin into the bloodstream, which can trigger acute kidney failure, heart arrhythmias and death when combined with extreme exertion and heat exposure, per the CDC. The agency identifies physical exertion in hot environments as a primary risk factor for the condition.
Untreated exertional heat stroke carries a mortality rate of up to 80 percent among athletes and military trainees, making immediate rapid cooling on-site, such as ice-water immersion, the single most critical intervention to prevent irreversible organ failure, according to the British Journal of General Practice. The condition remains among the leading non-traumatic causes of death in rigorous training programs. A retrospective military cohort study published by the National Institutes of Health documented an annual incidence rate of 22.2 cases of exertional rhabdomyolysis per 100,000 recruits during basic military training, illustrating how common the underlying injury can be in demanding physical preparation programs of the kind Stallman had joined, per PMC.
