After a month of searching, man learns from NBC News that DHS sent his brother to El Salvador

A Venezuelan in the U.S. and his family back home had been frantically looking for answers over what he called the "forced disappearance" of his brother, Neiyerver Adrián Leon Rengel.

It was March 13 when Nedizon Alejandro Leon Rengel called his brother Neiyerver Adrián Leon Rengel to wish him a happy birthday.

Alejandro never heard back from him. Federal agents detained Adrián on his way to his job at a Dallas barbershop. 

For the next five weeks, Alejandro has searched for Adrián, trying to learn where he was: deported to another country? Held in an immigration facility in the United States?  

He and Adrián’s live-in girlfriend called Immigration and Customs Enforcement in Texas, getting shifted from office to office with different responses. 

Sometimes they were told Adrián was still in detention. Another time they were told that he had been deported back to “his country of origin,” El Salvador, even though Adrián is Venezuelan. (Alejandro provided NBC News with audio recordings of the calls.)
