• Norberto Gustavo “Pino” Brondino, 55, a rural producer, remains in preventive detention after allegedly firing at police during a raid, with initial counts for resistance to authority and illegal weapons possession.
• Investigators report hairs and blood detected in Brondino’s pickup and traces at a nearby barn, while security cameras recorded his truck near Mendieta’s home the night she disappeared.

• Authorities are reviewing Mendieta’s private Instagram writings that depict a secret, conflicted relationship, which acquaintances and investigators view as contextual but not conclusive evidence.
