Two other people in the car suffered minor injuries, including the driver, Ronaldo Miranda. Miranda passed a breathalyzer exam after the accident that led to the death of Cristiano Araújo. Authorities are now investigating whether Miranda fell asleep at the wheel before the crash, which occurred early Wednesday morning. It also appears that the car was speeding before it flipped over.

Before his death, Cristiano Araújo  started his musical career by performing with twin Ana Cristina. He turned solo in 2010, rising to fame with his EP Efeitos. He later released his first album, Continua, in 2013, which included hit songs like “Caso Indefinido” and “Maus “Bocados.”
