DNA Confirms Teen’s Identity in Coghlan Grave as Witness Implicates Ex-Classmate

Fiscal López Perrando plans to summon Cristian Graf following DNA confirmation of the remains as Diego Fernández, supported by a witness testimony linking Graf to the 1984 killing.

Overview

  • Construction workers uncovered 150 bone fragments and personal items in a roughly 60-centimeter-deep grave at a Coghlan lot on May 20 adjacent to a former Gustavo Cerati rental.
  • Forensic experts from the Policía Científica and the Equipo Argentino de Antropología Forense dated the burial to the 1990s and identified a fatal stab wound to the fourth right rib along with marks of attempted dismemberment.
  • A DNA test matched the remains to 16-year-old Diego Fernández, who disappeared near Belgrano on July 26, 1984, resolving a 41-year-old missing person case.
  • A surprise witness living abroad informed authorities that Cristian Graf, son of the homeowners and a former schoolmate of Diego’s, was involved in the disappearance.
  • Fiscal Martín López Perrando has classified the case as “averiguación de delito” and is preparing to summon Graf for questioning despite the prospect of statutory prescription.
