COVINGTON, Ky. -- A Kentucky judge has declared a mistrial in the case of two lawyers charged with defrauding clients of $65 million in a diet-drug settlement.

The ruling came Thursday after jurors said they were deadlocked.

The case has been closely watched in the horse racing industry because Gallion and Cunningham are part-owners of 2007's Horse of the Year, Curlin.

The jury had considered the case against suspended lawyers William Gallion and Shirley Cunningham Jr. for eight days.

A third defendant was acquitted earlier this week, all faced a single charge of conspiracy to commit wire fraud.

Jurors were dismissed and left without commenting.

Judge William Bertelseman ordered Gallion and Cunningham sent back to jail.
