Caitlyn Jenner said she is going through “tough times” following the July 2 death of her longtime friend and manager, Sophia Hutchins, who was killed when her speeding all-terrain vehicle (ATV) lost control on a winding road near their Malibu home and plummeted into a ravine.

Hutchins was driving the vehicle near Jenner’s $3.5 million Malibu condo when she collided with the bumper of a moving car on Wednesday morning.

According to Daily Mail, which spoke with Sgt. Eduardo Saucedo of the Los Angeles County Sheriff's Department, the 29-year-old rear-ended a sedan on a winding stretch of Decker Canyon Road, lost control, and veered off the side of a cliff, plunging more than 350 feet into a ravine. She was pronounced dead at the scene.
