Agents from the McAllen border patrol station arrested Jose Mendez-Hernandez, a Mexican national, near Havana, Texas, on Nov. 13.
Mendez-Hernandez has been attempting to enter the U.S. illegally when officers apprehended him, the report says.
After doing a background check on Mendez-Hernandez, officers learned he had previously been arrested and sentenced to more than 20 years in prison for murder by the San Diego County Sheriff’s Office.
Three days later, on Nov.16, McAllen agents arrested a second Mexican national, Jaime Cantu-Leal, near Mission, Texas.
Background checks again revealed that Cantu-Leal had been arrested by the McAllen Police Department in 1994 for murder and was subsequently convicted and sentenced to 18 years in prison.
Border Patrol is now processing both Mendez-Hernandez and Cantu-Leal accordingly, the report notes.
However, illegal immigrants from Mexico have recently fallen to less than half of the undocumented population for the first time since 1990.
Illegal border crossings have also significantly declined in the latter part of this year, down from a high of 144,000 in May to 52,000 in September, which is credited in part to new asylum restrictions and Mexico tightening its border.
Earlier this year, Trump’s administration enacted the Migrant Protection Protocols, or MPP, also known as the “Remain in Mexico” policy. The MPP requires asylum seekers to stay in Mexico while their claims are processed.
The department said that MPP has proven to be an “indispensable tool in addressing the ongoing crisis at the southern border and restoring integrity to the immigration system.” More than 55,000 aliens have returned to Mexico.
