Overview
- Law enforcement uncovered the alleged plot after intercepting WhatsApp messages in which the detainees discussed killing prosecutor María Paula Hertrig and shared photos and details of her movements.
- The probe began from an August 26 complaint into a gang that duplicated car keys and escalated in mid‑September when messages tied the suspects to a plan of retaliation against the prosecutor.
- Authorities identified the suspects as Martín Darío Rettori, 42, and Ariel Ernesto Libertini, 47, who remain in separate penitentiary units in Florencio Varela and Campana.
- At the request of San Isidro Attorney General Patricio Ferrari, police searched the inmates' cells, seized three cellphones, and opened digital forensic examinations that could produce new charges or arrests.
- Hertrig leads the UFI de Boulogne and has had recent public exposure for the Ernestina Pais probe, and the case highlights the ongoing problem of inmates using contraband phones to coordinate crimes from inside prisons.
