KNOXVILLE, Tenn. -

Campbell County attorney Johnny V. Dunaway has pleaded guilty in federal court to filing a false tax return.

Dunaway faces up to three years in prison and could be ordered to pay restitution to the Internal Revenue Service. A sentencing hearing is scheduled for April 23.

Dunaway admitted failing to truthfully declare business income from his law practice in 2008 and was disbarred by the state Supreme Court in October.

The high court previously censured Dunaway for charging a contingent fee from a client for an appeal under circumstances that violated the rules of professional conduct.
