The resignation of Gómez Trejo adds to the massive confusion created by the López Obrador administration in its attempt to deny the "historical truth" about the missing 43 students. So far, this new investigation has failed to find any substantial evidence and has instead focused on promoting persecution against public servants, military personnel, and media.
Though Gómez Trejo was a symbol of the López Obrador administration's efforts to finally reveal the truth about what happened to the 43 missing students, setbacks were expected from the start due to the original investigation and political interests related to this crime. Breakthroughs have already been made, and soon the truth will be revealed.
Gómez Trejo's resignation exposes a rupture within the ongoing probe. Without clear guidelines on who and what to investigate, internal disputes between prosecutors will only lead to anger and compromise the investigation.
