A Tioga County jury could not reach a unanimous decision in the trial of Kenneth Williams, 47, of Owego.
Williams is a village of Owego trustee.
He was on trial for rape and sex abuse involving two girls.
Prosecutors claim he sexually abused a 3 year old girl at his home in 2005.
His wife ran a daycare center out of the couple's home in Owego.
In a separate case, a girl claims Williams raped her at the home in 2003 when she was 4 years old.
The jury began deliberations on Friday and deadlocked on a verdict.
The judge declared a mistrial.
