Overview
- Jonathan de Lima, 33, disappeared on December 31 after entering the water near the Pejerrey Club pier in Quilmes.
- A lifeguard had warned the group about a strong current before they went in; two friends made it out, one with help from rescuers.
- Prefectura Naval, Defensa Civil, municipal lifeguards, volunteer firefighters and other teams have maintained continuous river and shoreline sweeps.
- Elevated river levels and turbidity have reduced underwater visibility and forced nighttime suspensions of the search, with no trace located after 48 hours.
- The Naval Hydrography Service reported the early January rise in water level, while family members circulate appeals for information on social media.
