Ryan Breaux, the younger brother of Grammy award-winning artist Frank Ocean, is believed to have died early Sunday morning in a single-vehicle car crash, reports KCAL 9.

Officers responded to a call of smoke in the Thousand Oaks area around 1:30 a.m. on Sunday. By the time police arrived at the scene, the car was enflamed. The car, which was heading southbound on a curved street, veered off the road and hit a tree in the center median, reports the Thousand Oaks Acorn. The Tesla split in half upon impact, according to Ventura County sheriff’s deputies.

An investigation into the cause of the crash has begun. Police believe speed may have contributed.

“The speed limit is north of 45 mph,” Ventura County Sheriff’s Deputy Wendell Campbell told KTLA. “It’s a nice big stretch of road, so sometimes people do pick up speed.”

Investigators are also looking into whether drugs or alcohol may have been a factor.
