The Goodpasture cross county runner who collapsed Oct. 16 during a recreational run died of natural causes, according to an autopsy report.
The medical examiner's office in Nashville ruled Moss' death natural caused by cardiac dysrhythmia due to microscopic myocardial. She was 18.
Cardiac dysrhythmia due to microscopic myocardial, where scar tissue builds up, most notably following a heart attack. In some cases, the scar tissue can develop and lead to heart failure.
Moss is among three runners from Middle Tennessee who died during the TSSAA cross country season.
Thompson Station Middle School's Kate Rust, 13, died Sept. 18 while Sycamore cross county runner Tristin Franklin died Aug. 27.
Moss was a senior at Goodpasture who was also a swimmer and cheerleader. She qualified for the 100-yard backstroke state final at the 2024 TISCA state championships.
She was known by virtually everyone at the small private Christian school in Madison, where her family ties go back nearly five decades.
Moss' grandfather, Ted Bloodworth, worked at Goodpasture for 49 years as a teacher, coach and ultimately the school's first admissions director. Moss' mom, JaneAnne, is a third-grade teacher there. Moss' two younger siblings are in the school system.
The line for her visitation at the Hendersonville Church of Christ stretched outside with attendance ranged from 800 to 1,000 people.

During Moss' celebration of life, it was revealed she had been selected weeks prior by faculty as the 2024 Miss Goodpasture, the school's prestigious award given to a person who best characterizes Goodpasture in academics, athletics, extracurricular activities and spirituality.
Moss loved family trips and hated the idea of missing one. She took multiple mission trips to City of Children, a children's home in Mexico, and would not hesitate to pause her sports to share her faith.
But Moss' faith was her top priority.
"Janie Grace led her life following Jesus' footsteps. That's who she was," Goodpasture president Jeff Bixenman previously told The Tennessean. "This was a person who went out on top. (Her funeral) was a true celebration of life, because we know where she's at right now, because she lived her life the right way."
