Amnesty International’s research has found that investigations into feminicides preceded by disappearance in the State of Mexico are failing because evidence is lost, the level of investigation is inadequate and a gender perspective is not applied correctly. In addition, families are re-victimized because they have to spend time and money investigating cases themselves or putting pressure on the authorities to investigate. They are also re-victimized by the frequent threats and harassment they face from the perpetrators and sometimes also from the authorities.
