The cause of death for Sophia Hutchins, a close friend and manager of Caitlyn Jenner, has been disclosed following her tragic death in a California ATV accident two weeks ago.

The 29-year-old, who was also a former surrogate for the Trump campaign, succumbed to blunt force trauma, according to her death certificate issued by the County of Los Angeles Department of Public Health, as reported by TMZ.

Her death was ruled an accident.

On July 2, while riding her quad near Jenner’s $3.5 million Malibu condo, Hutchins collided with the bumper of a moving vehicle. The collision resulted in her being thrown off the path and down a 350-foot ravine.

Emergency responders pronounced her dead at the scene. 

No one else was injured in the crash.

Police suspect Hutchins was speeding when she rear-ended the gray 2016 Mazda 6 carrying two women. 

“It looks like she may have been speeding and rear-ended the other car, the other party, and then that caused her to veer to the right and go off the cliff,” Sgt. Eduardo Saucedo of the Los Angeles County Sheriff’s Department previously told the Daily Mail.

“It doesn’t seem like she was following them. I think she just, she came up on them and then hit the car. So it looked like she tried to maneuver to go around it, but she was going too fast and just ended up clipping the rear end of that Mazda, causing her to veer off and go off the cliff there.”

Footage captured by KCAL News showed a blue ATV lying next to an upside-down vehicle that had previously crashed in the same spot.

Saucedo said the 75-year-old Olympian was at the grisly scene when authorities arrived.

Jenner and Hutchins, who was also transgender, first met in 2015 after the “Keeping up with the Kardashians” alum announced her own transition.

Hutchins, who appeared in several episodes of Jenner’s hit “E!” docuseries “I Am Cait,” credited the gold medalist’s coming-out journey with motivating her to transition in 2016.

The Pepperdine University alum founded the sunscreen company Lumasol after graduating in 2017.

Two years later, she moved in with Jenner, who was 46 years her senior, and became her manager — sparking a slew of dating rumors the pair both repeatedly denied.

Hutchins later served as a surrogate for Trump’s presidential campaign in 2024, where she made several television appearances in support of the then-former commander-in-chief.

Jenner and Hutchins were later spotted at Mar-a-Lago for an election night watch party.

Hutchins will reportedly be laid to rest at Holy Cross Catholic Cemetery in Los Angeles on July 24.
