Overview

• More than 80 collectives and human-rights organizations pressed CNB head Martha Lidia Pérez Gumercindo to immediately bring in outside specialists for searches and identifications.
• Families accuse the CNB of acting as a secondary observer with inadequate expertise, leaving relatives to gather leads and evidence with little official support.
• An independent technical review requested by Hasta Encontrarlos disputes the scientific validity of CNB work in Oaxaca, citing incorrect georadar selection, weak sampling methods, and incomplete data processing.
• Relatives and advocates say search operations overemphasize locating graves and neglect the presumption of life, noting Supreme Court guidance tied to the Reyes Amaya and Cruz Sánchez case.
• The groups point to a forensic crisis with about 72,000 unidentified remains in state custody and cite laws guaranteeing families’ access to independent peritos financed or facilitated by the state.
