Overview
- The remains first came to light during construction on May 20, 2025, when workers uncovered bone fragments in a Coghlan garden that were later linked to Diego Fernández Lima by the EAAF and DNA comparison with his mother.
- Forensic work found 151 bone fragments, a stab wound to the chest, signs of an attempted dismemberment and personal items such as a Casio calculator watch and a school tie, and an autopsy concluded the death was violent.
- On November 28, 2025, an appeals chamber revoked the prior sobreseimiento of Norberto Cristian Graf and ordered the investigation be reopened with homicide as the primary hypothesis.
- A georradar survey carried out on May 4, 2026, by Gendarmería’s prospection division identified a geophysical anomaly next to the original excavation and recommended controlled excavations; a judge has frozen changes to the backyard pending decisions.
- The family has gained long‑sought identification and a burial site but investigators say new digs could yield more physical evidence that might strengthen criminal charges or clarify who was responsible.
