DILLEY, Texas -- Last month, Kelly Ocampo believed she received good news: Her 21-year-old pregnant sister had finally been granted bond and was going to be released from the family immigration detention center in Dilley, Texas.

The letter she received from a lawyer to whom she had paid more than $3,000 was written on U.S. Immigration and Customs Enforcement letterhead and stated that the ICE bond for Maria Alejandra Gomez-Quiroz was approved.

"This notice confirms that the immigration bond ordered by the Immigration Court has been successfully paid through an official payment method authorized by the U.S. Department of Homeland Security (DHS)," the letter stated.
