Palm Beach Clerk & Comptroller Sharon Bock is taking no chances.

As a federal grand jury indicted three high-volume investors for allegedly rigging auctions, Bock and her staff audited Palm Beach County's procedures to look for vulnerabilities in the judicial foreclosure sales process.

Prosecutors didn't allege a system failure or breach in the technology used by Palm Beach Circuit Court to host online real estate auctions. The indictment instead claimed investors Avi Stern, Christopher Graeve and Stuart Hankin conspired to rig bids submitted for judicial sales from at least January 2012 to June 2015.
