Cash shortages, unpaid bills and neglected refunds turned up when State Comptroller Thomas P. DiNapoli’s office audited the records of Otto Town Clerk Betty A. Huber, according to a report released Thursday.

Auditors discovered a cash shortage of $4,134 that had not been detected and $2,400 in duplicate tax payments that had not been refunded to property owners in the Cattaraugus County municipality.

The auditors also noted that “the clerk had no record of payment or enforcement of unpaid sewer bills totaling approximately $8,500, including her own, which totaled $950. The clerk also discarded tax stubs, which prevents auditors from verifying if she paid $970 of her own taxes.”

The audit pointed out that Town Board members and the town clerk failed to make corrections after similar audit findings in 1999 and 2001.
