A 20-year old Guatemalan woman seeking asylum and sent to Mexico under a controversial Trump administration policy died early Tuesday morning after attempting to re-enter the U.S. in El Paso, a spokesperson for U.S. Customs and Border Protection told CBS News.

The woman, Vilma Mendoza, had initially entered the U.S. on July 4 and had been awaiting her asylum hearing in Mexico under the Migrant Protections Protocol program, according to a Guatemalan consulate official. She attempted to re-enter the U.S. on July 29 through an irrigation canal where she drowned. Her asylum court hearing was scheduled for August 18th.

A CBP spokesperson said Border Patrol agents were told about Mendoza by an Ecuadorian man they had apprehended. "The man informed agents that he had entered the canal with a woman, who did not make it across," the spokesperson said. "A rescue team from the El Paso Fire Department performed CPR and transported the woman, later identified as a 20-year-old from Guatemala, to a local hospital, where she was pronounced deceased shortly after midnight."
