The three deceased from the Cybertruck crash in the Bay Area's Piedmont enclave in November had been drinking and using cocaine, toxicology reports show.

The teenagers perished when the vehicle collided with a tree and erupted in flames, causing Dixon and passengers Krysta Tsukahara, 19, and Jack Nelson, 20, to die from smoke inhalation, according to the autopsy reports. All three suffered serious burns and were pronounced dead at the scene.
