Frank Ocean’s mother is mourning the death of her son Ryan Breaux, who was killed in a fatal car crash over the weekend.

On Wednesday, Katonya Breaux returned to social media to share a photo of her 18-year-old son embracing his mother. The grieving mom did not caption the post, but friends and fans shared their condolences in the comments.

Ryan and his former classmate Ezekiel “Zeek” Bishop, 20, were driving a Tesla in Thousand Oaks, Calif. when it veered off the road and collided with a tree in the center median just after 1:30 a.m. on Sunday. The force of the crash caused the car to burst into flames. They were both pronounced dead at the scene.

The victims were graduates of the Oaks Christian High School Class of 2019. Bishop was a freshman at Cal State Northridge, and played for the OCHS football and track teams.

It’s unclear who was behind the wheel or what caused the crash but speed could have been a factor, according to authorities.

Friends and former classmates took to social media to share heartfelt tributes including Kaia Gerber. “ryan and zeek, my heart is so heavy right now. I can’t put into words how grateful I am for every second I was lucky enough to spend with you,” the model wrote alongside a series of photos. “The two people who made me smile the biggest. I will never forget that. I can still feel you here. I can still hear your laughs.”

Added Gerber, “I promise to keep trying to smile for you, I love you both forever. rest peacefully always by each other’s side.”
