Illegal migrant accused of shooting off-duty CBP officer in NYC was only vetted over Zoom before being set free under Biden admin - sources | 23 July 2025 | The illegal immigrant accused of shooting an off-duty border officer in a Manhattan park was only vetted using Zoom before being released into the US under the Biden administration, The Post has learned. Dominican Republic national Miguel Francisco Mora Nunez, 21, waltzed across the U.S.-Mexico border into Arizona in April 2023 -- during the raging migrant crisis that saw federal agents take drastic measures in an attempt to free up resources. That month alone, the U.S. saw a wave of more than 183,000 migrants come across the southern border. "The whole system was overwhelmed by what the Biden administration was allowing," Charles Marino, former senior law enforcement adviser to DHS Secretary Janet Napolitano, told The Post.
