something that had put the parents on alert, as the strangers had been taking photos of the students; h) on September 29, 2011, a truck passed in front of the petitioners´ home, with the former President of Comitán and his bodyguards, who were allegedly involved in the events of November 8, 2009; i) on October 3, 2011, strange vehicles were seen apparently following the petitioners and prowling around their home; j) on October 17, 2011, one of Margarita Martínez Martínez’s bodyguards resigned, a fact that was reported to the competent authorities and, at the time of submitting the request for the provisional measures, the guard has not been replaced. According to the petitioner, she was to be assigned at least eight bodyguards, four on the day shift and four on the night shift. Given that the number of guards is insufficient to protect all the family members and that the petitioners are sometimes left unprotected, they felt that they were at risk and vulnerable. They also mentioned certain failings with regard to the transport and that the video cameras were not functioning; k) on October 20, 2011 Margarita Martínez Martínez received a threat at her home warning her that "[j]ust so you know there is no justice, better to [s]hut your mouth if you don’t want to disappear, we are the law and we are protected, death, death, death”; and l) on October 21, 2011, the representatives filed a third petition for the Commission to request provisional measures in favor of Margarita Martínez Martínez, Adolfo Guzmán Ordaz and their two children, Ada Saraí Martínez Martínez and Eduardo Abel Leon Martínez, in relation to the events that occurred on October 17 and 20, 2011.

The Commission’s arguments to support its request for provisional measures are: a) the extreme gravity of the actions, threats, stalking, and harassment to which Margarita Martínez Martínez, Adolfo Guzmán Ordaz and their family have been subjected, presumably in retaliation for Mrs. Martínez Martínez´ activities as a human rights defender and for denouncing her own situation. The warning of further violence given the threat received on October 20, 2011, “the continuity of the alleged stalking, the lack of investigation of the facts that gave rise to the precautionary measures and a number of failings in the protective measures provided by the State, suggests that the situation of the [petitioners] is at a much higher level of gravity.” It added that the information provided by the petitioners indicates that the perpetrators of these acts are aware of their circumstances and activities; b) that Mrs. Margarita Martínez Martínez’s children are in a situation of grave risk which requires special measures of protection in response to their situation of vulnerability. The Commission found clear evidence that the stalking includes the activities of the two children and that the threats also extend to them. Therefore, the 4
