Thomas Kontogiannis, serving prison time for his role in laundering bribe money for former US Representative Randy “Duke” Cunningham, was sentenced yesterday to 12 years and 10 months in a $92 million real-estate scheme.

Kontogiannis, 62, led a scheme to defraud Washington Mutual Inc. and Credit Suisse Group AG’s DLJ Mortgage Capital in connection with the development of properties in Brooklyn and Queens, said prosecutors. He pleaded guilty in the scheme last year.

The fraud began in March 2003 and ran until Sept. 2007, prosecutors said.
