A Virginia man has admitted embezzling at least $400,000 from Dave Matthews Band violinist Boyd Tinsley.

Court documents say Getty Andrew Rothenberg pleaded guilty Tuesday to wire fraud in federal court in Charlottesville.

The documents say the 39-year-old Richmond man embezzled the money while working as a personal assistant and financial manager for a person identified only as "CBT." The U.S. attorney's office confirmed the person was Tinsley.

Rothenberg's duties included paying personal bills and expenses and directing investments. He submitted fraudulent or inflated bills and used the excess money for personal use.

Rothenberg faces up to 30 years in prison. Sentencing is set for Sept. 17.
