David S. Goldhirsh is a Brooklyn-based defense attorney specializing in federal criminal cases. He was a significant figure, co-conspirator, and cash courier in the international money laundering and public corruption investigation known as 'Operation Bid Rig III' (also referred to as Operation Bid Rig). He operated a charitable organization or 'gemach' called Boyoner Gemilas Chesed (BGC), serving as its operator and primary signatory on the accounts. This entity served as a conduit for laundering large sums of illicit cash through an underground money transfer network that connected Brooklyn and New Jersey to Israel and Switzerland. Between May 2008 and July 2009, he conspired with Rabbi Mordchai Fish and Lavel Schwartz to launder funds for an FBI cooperating witness, Solomon Dwek. Goldhirsh was identified as a key provider of physical cash in this network, moving approximately $100,000 for money laundering transactions linked to Rabbi Mordchai Fish. His involvement included accepting bank checks from Dwek—represented as proceeds from illegal businesses such as bank fraud and the trafficking of counterfeit goods—and providing cash in return, minus a fee of approximately 10%. He provided cash through the network in exchange for checks made payable to BGC and other gemachs. He was noted for meeting with co-conspirators in clandestine locations, including a mikva in Williamsburg, to facilitate these transactions. The case involved laundering approximately $795,000 in such illicit funds. Indicted in April 2011 on 14 counts including money laundering conspiracy and operating an unlicensed money transmitting business, Goldhirsh pleaded guilty in June 2012 to one count of operating an illegal money transmitting business. In January 2013, he was sentenced to one year in prison, three years of supervised release, and forfeited $154,289. Post-sentencing information on Goldhirsh's activities is limited, with no further public legal troubles reported as of available records.
