Losses Climb for Homeowner Groups - washingtonpost.com
Another one of those isolated instances:

RICHMOND, July 19 -- At least $2 million was stolen from Northern Virginia condominium and homeowner associations, probably by a top executive of the Fairfax City company hired to manage their finances, a forensic accountant told state regulators at a hearing Thursday. The losses sustained by customers of Koger Management Group between 2004 and 2006, described in a report to the Virginia Real Estate Board, far exceed earlier estimates of $800,000. The total may grow as more homeowner associations conduct audits, said Jeffrey D. Barsky, the accountant appointed by the board to investigate the matter.
