The moniker "BGC Boys" surfaced not in the polished boardrooms of Bonifacio Global City but in the surveillance logs of high-stakes gambling floors across Metro Manila and Pampanga. It refers to a specific cell of engineers from the Department of Public Works and Highways (DPWH) Bulacan 1st District Engineering Office. Senator Panfilo Lacson identified this group as the "Bulacan Group of Contractors" in a privilege speech on September 9, 2025. Our forensic analysis of Anti-Money Laundering Council (AMLC) data and Philippine Amusement and Gaming Corporation (PAGCOR) records confirms that this clique executed one of the most brazen laundering operations in Philippine history. They funneled P950 million in flood control kickbacks directly into slot machines and baccarat tables between 2023 and 2025.

The core members of this group held mid-level positions that theoretically offered no access to such liquidity. The ringleader was identified as District Engineer Henry Alcantara. His primary lieutenants included Assistant District Engineer Brice Ericson Hernandez and Construction Division Chief Jaypee Mendoza. Engineer II Arjay Domasig and contractor Edrick San Diego completed the inner circle. Their collective salaries did not exceed P6 million annually. Yet their rolling turnover in thirteen casinos exceeded P1 billion over twenty-four months.
