SACRAMENTO, Calif. -- A jury came to a verdict Tuesday involving the last remaining defendant in a corruption case that brought down the sheriff of San Joaquin County.

The former lobbyist was accused of extortion, fraud, and other charges involving efforts to build a Stockton power plant.

Monty McFall, 58, was convicted Tuesday on nine counts of attempted extortion, six counts of honest services mail fraud and two counts of witness tampering. And he was acquitted of three counts of honest services mail fraud following a five-week trial, according to a news release from the U.S. Department of Justice.

In January, Sheriff Baxter Dunn and three other men -- N. Allen Sawyer, Lynn Bedford and Tyler Reves -- pleaded guilty to related charges and agreed to testify against McFall. However, McFall has continuously denied the accusations, with his attorney arguing that he was only guilty of aggressive lobbying, according to the release.

"The jury's conviction of Monte McFall brings to an end a saga of greed and corruption," said United States Attorney McGregor Scott. "The people of San Joaquin County are the better for it. I extend my highest praise for the San Joaquin District Attorney Investigator's Bureau, the FBI and the prosecutors from my office for their tireless work in routing out corruption in San Joaquin County. Because of their efforts, a sitting sheriff, a former supervisor and his staff member, and a former state criminal justice official now stand convicted for misdeeds they committed while they enjoyed the public trust."

"Today's verdict marks a significant and hopefully final step toward re-instituting political integrity within various segments of San Joaquin County government," said FBI Special Agent Keith Slotter said in the release. "This investigation and prosecution serve notice that corruption among elected officials will not be tolerated and serves as a large measure of justice and hope for the entire San Joaquin community."

Bob Heidelbach who was appointed sheriff after Baxter Dunn plead guilty in the case said it's time for San Joaquin County to move forward and not forget the lessons learned, which include the abuse of power.
