Boyoner Gemilas Chesed (also known as Boyen Gimilas Chesed or BGC) was a Brooklyn-based Jewish charitable loan society (gemach), specifically an interest-free loan fund, which also operated in Newark, New Jersey. It was a similar gemach used in the same laundering conspiracy discovered during the FBI's 'Operation Bid Rig III,' functioning as the primary vehicle for laundering illicit funds through checks and facilitating the movement of money in Friedlander's network. The organization was controlled by Rabbi Mordchai Fish and operated by David S. Goldhirsh, serving as a sister gemach in the same laundering network involving Fish. For a fee—typically 10 percent—the organization would accept checks from 'clients' (including FBI cooperating witness Solomon Dwek) represented as proceeds from illegal activities, such as bank fraud and trafficking in counterfeit luxury goods, and return physical cash through an underground money transfer system. It maintained bank accounts at Capital One Bank in Brooklyn and JPMorgan Chase Bank in Newark. Federal court documents revealed that the gemach was used to launder millions of dollars between 2007 and 2009. In 2009, federal authorities seized over $146,000 from the organization's accounts as part of a criminal forfeiture action against its operators. Funds from Boyoner accounts were commingled into Gmach Shefa Chaim.
