Anthony Riley, a breakout contestant on season 8 of NBC’s The Voice, was found dead , the Philadelphia Inquirer reports. He was 28.

Riley, a beloved street performer in Philadelphia’s Center City, was chosen by all four judges within seconds of his audition, singing James Brown’s “I Got You (I Feel Good).” But he left the show after the first battle round in January to seek help for substance-abuse issues.

The Philadelphia police and reps for the singer’s coach on the show,Pharrell Williams, did not respond to requests for comment.
