Ex-Prosecutor Admits Negligence in Francisca Mariner Disappearance Case

Cancún, Quintana Roo — The former head of the Specialized Prosecutor’s Office for Forced Disappearance, Rosa María “N,” has accepted responsibility for omissions and negligence in the investigation of Francisca Mariner’s disappearance and requested an abbreviated procedure to determine her sentence. As part of the process, she issued a public apology to María Dolores Patrón Pat, the victim’s mother and leader of the Madres Buscadoras de Quintana Roo collective.

Rosa María “N” faces criminal proceedings stemming from alleged irregularities in the investigation that followed the missing person report for Mariner in 2020. During a preliminary hearing, she acknowledged that she failed to properly supervise the work of forensic experts, public prosecutors, and investigative police assigned to the case.

As a condition for the abbreviated procedure, she delivered the apology outside the State Prosecutor’s Office (FGE), admitting that institutional failures hampered the search for the victim and the fulfillment of due diligence. She stated that omissions in case management prevented timely technical actions needed to clarify the case and locate the young woman.

The case gained prominence in December 2024 when Mariner’s body was identified at the Forensic Medical Service (Semefo), where it had remained for four years due to a failure to cross-reference genetic profiles in a timely manner.

Criminal proceedings have been initiated against four former public officials, including Rosa María “N,” for alleged responsibilities arising from the irregularities detected during the investigation.
