Two of María Herrera’s children disappeared in 2008 and another two in 2010. Some time later, she rebuked former President Felipe Calderón for the damage that, according to her, was caused by the war on drug trafficking. Today she is one of the most visible voices of the families who are looking for her loved ones, who disappeared due to the violence. According to the National Search Commission, in Mexico there are more than 107,000 cases like that of María Herrera. Carmen Aristegui spoke with the activist to find out the scope of a lawsuit request that she filed with the Inter-American Commission on Human Rights (IACHR).
