On 14 August 2026, Marcos Emiliano Cayupán, a repeat offender serving more than two years for multiple robberies at the Alcaidía UR-I in Santa Rosa, La Pampa, returned from his second 48-hour day-release and presented himself for the mandatory re-entry search.[1] Guards found five small black nylon packets in his mouth containing compact marijuana, which he had hidden to evade the search.[1]
Judge Mónica Rivero, the substitute execution judge, immediately revoked his day-release benefit, ruling he had gravely violated the absolute prohibition on possession and use of drugs imposed as a condition of his release.[1]
His official public defender Juan José Hermúa appealed the revocation to Sala B of the La Pampa Penal Tribunal de Impugnación, arguing there were no surveillance cameras in the search room and no seizure records, photographs or medical examinations to prove the substance.[1] Sala B of the La Pampa Penal Tribunal de Impugnación, with judges Piombi and Frigerio, rejected the appeal and upheld the revocation, reasoning that it is normal for privacy reasons that intimate-search rooms have no cameras, and that returning to the institution in a way that shows an intention to introduce drugs and evade regulatory controls constitutes a concrete negative impact on the progressive sentencing regime.[1]
Cayupán must now serve the remainder of his sentence continuously in prison; his sentence ends in November 2027.[1]
