Other victims identified in the crash include passengers Lucas Vignale, Gaspar Prim and Lucas Brito Chaves, and pilots Alexandre Souza and Charles Marsillac, according to CNN Brazil.

Tree made eerie comments about his will just weeks before his death.

During an appearance on the "Zach Sang Show" in April, the 32-year-old singer opened up about what he wanted to happen to his wealth after his passing.

"I don’t believe that any of the wealth, or the things that get made from it, is mine," the singer said. "So when I die, my will is set up that when I pass, my family, no one’s going to get a penny."

"I’ll get my kids through college. That’s the agreement," he continued. "But there’s not going to be a silver spoon."

Tree, who set up his foundation before his death, said he wants his money to "go back to artists."

"You’re not allowed to buy equipment with the money. You’re not allowed to go get education and schooling with the money," he said. "You have to physically hire people to physically produce stuff — and you’re allowed to rent equipment to make things.

"I have basically a committee that I’ve set up when I pass — and I plan to do it while I’m alive — where basically everyone will vote on who the money goes to each year."

"But there’s room for other money, because when I die, my art will have residual value and will probably be worth more than it is now," he added. "People will finally appreciate my stupid f---ing videos and my stupid f---ing songs. That’s when people appreciate you, when you’re not there anymore."
