MEXICO CITY — She still relives the day the police officers shoved her to the back of a bus. Three of them stood over her.

“They ripped my pants off, started biting my arms, my breasts, my lips, then they penetrated me with their fingers, taking turns,” said Norma Aidé Jiménez Osorio.

She was an art student at the time, a witness to a police crackdown on a social protest movement in the town of San Salvador Atenco 11 years ago. Then she became a victim.

Ms. Jiménez, now 34, embarked on a decade-long struggle for justice that is finally moving closer to resolution. The Inter-American Court of Human Rights is considering the case of Ms. Jiménez and 10 other women who were sexually abused, tortured and jailed, their lives irrevocably altered.
