Fragments of what's believed to be Beethoven's skull were in a drawer in California for decades

CARMICHAEL, Calif. – Bone fragments believed to be from 18th-century composer Ludwig van Beethoven have made their way back to Vienna after living in a locked drawer of a home in Carmichael, California, for the past 30 years.

Paul Kaufmann's remarkable journey in taking possession of the curios began in 1990 following the death of his mother.

She lived in a town in the south of France. After traveling there and going through her belongings, he would find a key — and that key would not only open a safety deposit box, but inside reveal a second box full of mysteries.
