Claudia Medina Tamariz was asleep in her home in the Gulf coast port of Veracruz with her husband when Mexican marines burst in and arrested them both in August 2012.

Blindfolded and handcuffed, Medina believes she was taken to a local navy base where her captors accused her of working with organized crime. Over a period of hours, she says, she was beaten, sexually assaulted, jolted with electric shocks and subjected to simulated drowning. Two independent medical examinations found evidence consistent with her version. She was forced to bathe in front of her captors.
