Overview

• A federal grand jury charged 21-year-old Miguel Francisco Mora Nunez with possession of ammunition by an illegal alien and 22-year-old Christhian Aybar-Berroa with accessory after the fact for the July 19 ambush.
• DHS surveillance footage shows the pair riding a moped into Fort Washington Park, firing at the off-duty Customs and Border Protection officer and his companion before the agent returned fire.
• Both suspects were taken into custody by July 20, with Mora Nunez treated for a gunshot wound and Aybar-Berroa arrested after dropping off his accomplice at a hospital.
• Authorities say both men entered the U.S. without authorization—Mora Nunez through Arizona in 2023 and Aybar-Berroa through Texas in 2022—and have prior arrests for violence and robbery.
• Officials contend the case underscores federal enforcement priorities and has intensified calls for stronger federal–local collaboration on immigration and public safety.
