At the time, his sister, Nicole Iris Brown, stated that he led a healthy lifestyle and had no known health issues, making the loss even more shocking. “He was holistic and healthy. We didn’t know of him being sick, so this is all pretty sudden,” she informed NBC News shortly after his death.“I hope people will remember that he was willing to help the younger generation,” she added. “He was always big on helping younger people start their careers and get themselves into the game. For him, it was just about the music, no matter who the artist was.”Brown’s decorated career included co-writing and co-producing the track “Mine” from Beyoncé’s self-titled visual album, which featured Drake.
