• Pablo Grillo’s mother told Judge María Servini that her son “is no longer himself,” describing that he barely speaks and does not eat, and she asked for justice.
• The letter, read on Julia Mengolini’s radio program, addresses the March 12 shooting during a protest and frames the family’s anguish as the court weighs responsibility.
• The investigation now proceeds under an attempted‑homicide classification after court filings and technical reports pointed to antiregulation use of a 38 mm gas projectile.
• Indagated before Judge Ariel Lijo, Héctor Guerrero admitted he fired and declared himself innocent, citing poor visibility and stone‑throwing, claims the querella disputes.
• The querella and the case file assert Guerrero fired horizontally with an FM gas launcher (serial 00660) toward demonstrators, while Grillo remains in rehabilitation at Hospital Rocca.
