The soulful street performer, who instantly won over all four judges with his electrifying rendition of James Brown’s “I Got You (I Feel Good),” took his own life.
According to Philly.com, the singer was found in the basement of the Center City apartment he was staying at with friends.
Riley’s friend, Robby Parsons, confirmed the news to Yahoo Music’s Reality Rocks.
“Anthony passed away Tuesday. He wasn’t found until yesterday [Friday],” he said. “His sister called me at 7:30 yesterday to tell me… I called the friend he’d been living with, Bobby Iovine, and Bobby was in tears. And he said, ‘Robby, it’s true.‘”
NBC told People magazine in a statement, "We are sad over the passing of Anthony Riley. We offer our deepest condolences to his friends and family during this very difficult time."
For the brief period he was on The Voice, Riley was a fan favorite, and chose musician Pharrell Williams to be his coach.
In March, Riley, a front-runner, suddenly left ‘the Voice’ to enter a rehabilitation center due to substance abuse.
Last year, Philly magazine named Riley the city's best street performer. "You notice a gorgeous stranger. Your eyes meet. And suddenly you forget why you were so stressed out to begin with. Riley is that good," they wrote.
