"They treated us so horribly, as though we were animals," she wrote in the letter, in which she called herself "anonimo," anonymous.
The account came via Grassroots Leadership, a nonprofit that describes itself as "a nationally recognized civil and human rights organization" that fights to "end prison profiteering, mass incarceration, and deportation." The group, which is circulating a petition to reunite separated families, posted the letter on its website on June 25. Four days later, the group posted several more accounts from women who had been separated from their children.
Grassroots Leadership volunteers met with the women in T. Don Hutto Residential Center in Taylor, Texas, organizer Bethany N. Carson told CNN. Those volunteers spoke to the women about writing the letters and "helped them figure out how to get the letters out," she said in an email.
"They were written to tell their experience publicly to ask for help in being released from detention and reunited with their children," Carson said.
