An Oahu mother and son were charged Thursday with violating federal mortgage fraud laws.

Victoria Batangan Rumbawa and Russell Batangan Rumbawa were not arrested, but have agreed to appear in court this week to be arraigned, said FBI Special Agent Tom Simon.

The duo devised a scheme to defraud and obtain money from lenders between February 2004 and January 2007, according to charging documents.

They violated federal laws by committing fraud across state lines and making false statements to get loans from financial institutions, the documents said.

Victoria Rumbawa recruited her son Russell and others to sign loan applications containing false information, the documents said.

The two worked with Esther Miguel, owner and president of Easy Mortgage, who was charged separately with 13 other Oahu residents for mortgage fraud in August.

In the three-year period, Russell Rumbawa signed five loan applications containing false information related to four separate homes in Salt Lake, Hawaii Kai and Waikele.
