Los Angeles authorities are investigating a fatal car crash involving Summer Wheaton.

The influencer and self-proclaimed “wellness advocate” has been identified as the driver behind a 2019 Mercedes-Benz that crashed into a 2020 Cadillac on July 4 in Malibu, authorities told KABC.

The incident occurred on the Pacific Coast Highway around 10:17 p.m., when the Mercedes-Benz crossed the center median and collided head-on with the Cadillac, according to a press release obtained by E! News.

Authorities said it’s unclear why the Mercedes-Benz left its lane.

“As a result of the collision, the driver of the Cadillac succumbed to his injuries at the scene,” officials stated. “The passenger of the Cadillac and the driver of the Mercedes-Benz were transported to a local hospital and treated for non-life-threatening injuries.”

An investigation into the crash is ongoing, per authorities.

Wheaton has not been charged with any wrongdoing. E! News has reached out to her rep for comment but hasn’t heard back.
