Caitlyn Jenner’s late friend Sophia Hutchins died at the age of 29 in a horror ATV accident in Malibu. 

Hutchins’ life was cut short on July 2 after she plunged 350 feet down a cliff on the vehicle after she was believed to have struck a car bumper.

On Wednesday her cause of death was shared.

A death certificate from the County of Los Angeles Department of Public Health, which was obtained by People, shows Hutchins died from ‘multiple blunt force injuries.’

The case remains open, but her manner of death has been ‘ruled an accident.’

The reality TV star will be laid to rest at the Holy Cross Catholic Cemetery in Los Angeles on July 24.

Hutchins was featured heavily in the reality series, I Am Cait. The series ran for just two seasons but it gave glimpses into Jenner and Hutchins’ unorthodox life together.

Later Sophia became the CEO and director of the Caitlyn Jenner Foundation.

In 2017, Hutchins moved into Jenner’s home and began working as the star’s manager in 2015.

Before that Kris Jenner managed Caitlyn.

DailyMail.com sources revealed that after striking the car’s bumper, the impact forced the ATV and Hutchins ended up ‘plummeting 350ft down into a ravine.’

First responders pronounced Hutchins dead at the scene.

Investigators told DailyMail.com that she was believed to have been speeding in the 2013 Polaris ATV, and was ‘side by side’ a Mazda when she rear-ended the car.

The impact caused the ATV to veer off the cliff off the winding mountainous road in Malibu.

The two individuals in the car struck by Hutchins and the ATV were not injured.

Hutchins was in Jenner’s inner circle for over a decade after she came out as a transgender woman in 2015.

Hutchins met Caitlyn that year and appeared in multiple episodes of the television documentary series I Am Cait, a spin-off of Keeping Up With The Kardashians.

Despite living under one roof, Hutchins previously told The New York Times that they ‘were never romantically involved’, insisting it was all about work and friendship.

‘Caitlyn is a parent to me. I have said that a million times. It is a parental, familial relationship,’ Sophia said.

In 2020, Sophia posed for an online ad campaign for Kim Kardashian’s highly successful clothing line SKIMS.

Sophia was particularly close to Kris Jenner, speaking to her regularly, and Hutchins also had a good relationship with Jenner’s daughters Kendall, 29, and Kylie, 27. The siblings once gave Sophia a stunning heart-shaped diamond necklace for Christmas.

‘I’m on good terms with all the family, but I’m closest with Kris, Kim, Kylie and Kendall’, Sophia said.

The tragedy comes nine years after Jenner was involved in a fatal car crash while driving on the Pacific Coast Highway in Malibu. The collision involved four cars and resulted in the death of Kim Howe, 70.

Jenner was not charged in the crash, but an investigation by the LA County Sheriff’s Office determined that Caitlyn was driving too fast. That opened her up to blame in civil lawsuits, which was later settled out of court.

Despite living under one roof, Hutchins previously told The New York Times that they ‘were never romantically involved’ with each other — a sentiment that pair have repeated over the years.

‘I don’t feel a need to address my sex life, quite frankly, unless I want to,’ Sophia sternly told the outlet at the time.

Hutchins’ last public appearance with Jenner was in 2024 when Sophia accompanied her to the April 2024 White House Correspondents Dinner in Washington, D.C.
