His disappearance occurred along with that of his younger brother, although the latter was subsequently released. Since then, his mother, Ceci Flores, became one of the most visible voices of the mothers' search movement in Mexico, fighting to locate missing persons and to highlight the issue. The discovery of the remains was initially announced by the activist herself, who shared on social media that she had found bone fragments that could belong to her son. However, at that time, official confirmation through genetic comparison was awaited. Family and collectives' reactions In the statement issued after the confirmation, the members of the collective expressed their pain and gratitude for the support provided throughout the process. They recognized the solidarity of other searching families, of the media that accompanied the case, and of those who shared information to keep the demand for location alive.
