Isaac Melendez-Carranza, 31, a Salvadoran national, was arrested by the Loudoun County Sheriff's Office and taken to the Loudoun County Adult Detention Center in Leesburg, Virginia. The same day, ICE Washington lodged an immigration detainer and warrant of removal with the detention center, which honors ICE detainers under a 287(g) agreement. Border Patrol had previously encountered Melendez near Hebbronville, Texas, in 2016 after he crossed the Rio Grande from Mexico.
