Two helicopters collided Sunday in Rio de Janeiro, killing all six people on board, authorities in Brazil said. Among those believed to have died in the collision is American musician Oliver Tree.Tree’s name was on the flight manifest, according to The Associated Press as well as a police official with knowledge of the matter who spoke on the condition of anonymity because the investigation is still open.In a statement, the military fire department of the state of Rio de Janeiro said it responded to a call about 9am Sunday for a collision involving two aircraft in the southwest zone of Rio.According to the agency, the helicopters collided in mid-air and crashed into the parking lot of a car dealership where electric vehicles were parked, setting off a fire involving at least 20 cars.The agency did not identify the victims of the crash, and it was not immediately clear what caused the collision.Tree (32) had performed in Argentina this month as part of his world tour, AP reported.On Saturday, Tree posted a video to his Instagram account in which he appeared to be playing soccer in Brazil.A musician from Santa Cruz, California, Tree was recognised for his distinctive bowl cut and retro fashion along with his contributions to electronic music.He is best known for his songs Life Goes On, Miss You and Alien Boy. He has more than 11 million monthly listeners on Spotify.Representatives for Tree did not immediately respond to requests for comment. In a post shared on X, Britain’s Got Talent judge KSI said: “Can’t believe I’m actually having to type this. You’re 32 man. You should still be here. You still had so much life to live. So much music to make. So much content to make.“You’re a legend and will always be a legend. Still doesn’t feel real. Genuinely feel sick. I love you bro.”Jackass star Steve-O, real name Stephen Glover, paid tribute to Tree in a post on Instagram.Sharing a photograph of the two together, the US comedian and prankster said: “I was incredibly lucky to become friends with Oliver Tree.“He would check in on me regularly, and let me know he cared about how I was doing. Such a great person, f***, I’m going to miss him…” – The New York Times/AP
