Catalina “Xochitl” Santiago had already made it past the security line at the El Paso airport when two border patrol agents called her in for questioning and whisked her away to an immigration detention center.

Nearly a month after her arrest, she and her family still aren’t clear why she is detained. Santiago is a beneficiary of the Deferred Action for Childhood Arrivals (Daca) program – which has allowed her to legally live and work in the US.

“>They have no legal basis for why they detained her or why they’re holding her or why they’re trying to deport her,” said her spouse, Desiree Miller. And immigration officials have yet to provide her or her family any clear answers, she added.
