Bodybuilding star Andre Cavalcanti was tragically killed last week ... after he was involved in a horrific accident on a roadway in Brazil.
The crash reportedly happened on July 5 in the northern region of Parana ... when a 17-year-old allegedly took his parents' Volkswagon Virtus without their permission and went on a joyride with two other minors.
Cavalcanti was thrown from his ride and later pronounced dead at the scene.
