In mid‑July 2026 Argentine courts reported procedural developments in two separate high‑profile criminal cases. On 14 July, Judge Diego Anzorreguy was appointed to preside over the long‑running investigation into the 2024 disappearance of fashion designer María Cash. The case, now nearing its 15th anniversary, has seen multiple reversals, including the reinstatement of charges against truck driver Héctor David Romero after earlier dismissals. Prosecutors say sufficient evidence exists to resume prosecution, and the new judge will review pending measures such as witness testimony and technical analyses.

A few weeks later, on 29 July, authorities announced that the murder case of 25‑year‑old Diego Pérez in Villa Carlos Paz was moved to oral trial. After a period of delay caused by the illness of the overseeing control judge, the court confirmed that evidence was adequate to elevate the case. Police officer Fernando Reynoso faces homicide charges for the October 2025 collision that killed Pérez, and the next step will be the random assignment of a trial chamber and scheduling of a hearing date.

These updates illustrate a broader pattern of active judicial handling of prominent criminal matters in Argentina, with recent focus on judge reassignments, case reinstatements, and the progression of investigations toward trial.
