Musician Richard Swift, a former member of The Shins and The Black Keys, died Tuesday morning in Washington state, a representative for Swift tells CBS News. He was 41.

Last June, a GoFundMe page was set up to help him pay for medical bills as he recovered from a "serious medical condition."

A post on Swift's Facebook page read: "And all the angels sing 'Que Sera Sera.'" The representative said Swift's family would not be commenting beyond the post.
