Gabe Reilly, a 27-year-old Park City High School graduate and Salt Lake City firefighter-paramedic, died Sept. 27 in a wingsuit BASE jumping accident in Cache County.

Reilly jumped from a roughly 700-foot cliff near Leetham's Hollow in Millville Canyon with a group of eight to 10 people at about 9:10 a.m., according to the Cache County Sheriff's Office via KSL. His wingsuit did not generate enough lift, and he struck the ground at high speed. He was pronounced dead at the scene. Cache County Search and Rescue responded, and a Life Flight helicopter assisted in removing him from the area.

The sheriff's office described Leetham's Hollow as a popular spot for BASE (buildings, antennas, spans and earth) jumping.

Reilly grew up in Park City and raced with the Park City Ski Team before a knee injury ended his hopes of becoming an Olympic ski racer, according to his obituary. In high school, he wrestled and raced on the mountain bike team. He also took up Brazilian jiu-jitsu. He graduated from Park City High in 2017.

After earning a bachelor's degree in kinesiology from the University of Utah in 2021, Reilly became a firefighter with the Salt Lake City Fire Department. He served four years, following his father, Dan Reilly, who retired from the department in 2024, KPCW reported. In 2025, Reilly completed his paramedic training. He was also a gifted guitarist and singer.

The Salt Lake City Fire Department said in a statement that Reilly was known for his infectious smile, kindness and free-spirited nature. His commitment to the department, his fellow firefighters and the community would not be forgotten, the department said.

Reilly discovered skydiving in 2019 and went on to explore paragliding, speed flying, wingsuit flying and other forms of BASE jumping. He traveled widely, with a particular love for Lauterbrunnen, Switzerland. His father told The Salt Lake Tribune that one of Gabe's goals was to fly for AirMed, the University of Utah's air medical service.

On July 7, 2021, Reilly responded to a crash-landing by professional skydiving instructor Becca Critchfield in Tooele. Doctors later determined his actions saved her life. Critchfield told The Salt Lake Tribune that she owes Reilly everything.

Reilly was born Oct. 21, 1998, in Eugene, Oregon, one of triplets alongside his sister, Siri, and brother, Drew.

"He was always on the move, traveling around the world to skydive and wingsuit BASE jump and paraglide, and he truly loved to fly," Dan Reilly told The Salt Lake Tribune.
