A night-time boat trip on the Rio Grande river ended in tragedy when a speedboat collided with a pier and overturned, leaving passengers trapped underwater and six people dead, including a mother and her young son.
Authorities in Brazil confirmed that Viviane Aparecida Aredes, 35, and her four-year-old son, Bento Aredes Ferreira, were among those who lost their lives in the crash.
The accident occurred late Saturday on the Rio Grande river between the town of Rifaina in São Paulo state and Sacramento in Minas Gerais state.
According to local officials, a group of 15 people had set off earlier in the evening and were navigating the river after dark when the collision happened.
Investigators believe the driver may have lost control of the vessel before it struck a pier with significant force.
The impact caused the private speedboat to flip, throwing some passengers backward while others became trapped beneath the hull.
Witnesses described chaotic scenes as people struggled in the dark water.
Footage recorded shortly after the crash shows rescuers diving into the murky river in an attempt to free those pinned underneath.
Several men entered the water immediately, some using snorkelling equipment, as they searched beneath the overturned boat.
Emergency crews from the Fire Department and Military Police arrived and joined local residents in the rescue effort.
Nine people were successfully pulled from the river alive.
Three survivors were taken to hospital with minor injuries and later discharged.
Officials said only three of the 15 people on board were wearing life jackets at the time of the crash.
Police identified the six victims in the days following the incident.
Alongside Viviane and her son Bento, 22-year-old Marina Rodrigues Matias also died.
Juliana Fernanda de Oliveira Silva Ferreira, 40, and Erica Fernanda Leal Lima, 41, were named as additional victims.

The final victim identified was Captain Wesley Carlos da Silva, 45, who was reported to have been operating the vessel.
Authorities stated that investigators are examining whether he held the required nautical licence to pilot the speedboat.
The group had reportedly just left the Unico Floating Bar and were travelling toward a house in a condominium along the banks of the Jaguara reservoir when the accident occurred.
Hours before the tragedy, some of the victims were photographed smiling together at the floating bar.
Those images, shared on social media, have since become part of tributes circulating online.
Friends and family members have described Viviane as devoted and caring, someone who cherished time with her son.
Bento, just four years old, was remembered as lively and affectionate.
The Civil Police of Minas Gerais confirmed that a formal investigation is underway to determine the exact sequence of events leading up to the collision.
In addition, the Capitania Fluvial do Tietê-Paraná, a regional authority linked to the Brazilian Navy, announced that it has opened an administrative inquiry into the incident.
Officials are reviewing factors including navigation conditions, lighting near the pier, vessel speed, and safety compliance.
Some witnesses have claimed that the pier lacked adequate lighting or visible signage, though authorities have not yet confirmed those assertions.
Investigators are also examining whether alcohol consumption played any role in the events prior to departure.
The Fire Department reiterated the importance of wearing life jackets at all times while travelling on small recreational vessels.
They noted that the majority of those on board were not wearing flotation devices when the crash occurred.
Local authorities praised the rapid response of residents who entered the water to assist before emergency teams arrived.
Without that immediate action, officials said, the number of casualties could have been higher.
In Rifaina, businesses near the riverbank expressed solidarity with the victims’ families.
The Unico Floating Bar announced it would close for 24 hours as a mark of respect.
A neighbouring venue also said it would remain shut in mourning.
Community members have gathered along the riverbank to leave flowers and light candles in memory of the victims.
For families affected, the loss is immeasurable.
Viviane’s relatives said she was a loving mother whose life revolved around her children.
Marina, described as a close family friend, was remembered for her warmth and loyalty.
Juliana and Erica were both known in their communities and have been mourned by friends who shared messages of disbelief.
As for young Bento, tributes have focused on his bright smile and boundless energy.
Investigators continue to reconstruct the timeline of the journey, from departure at the floating bar to the moment of impact.
The river section where the crash occurred is popular for recreational boating, particularly during weekends.
Authorities have urged boat operators to exercise caution when travelling at night, especially near piers and docking structures.
They also emphasized the legal requirement for proper licensing and safety equipment.
The case remains under investigation by the Civil Police of Minas Gerais, with cooperation from maritime authorities.
Officials said findings from the administrative inquiry will help determine whether any regulatory breaches occurred.
In the meantime, families prepare for funerals instead of future gatherings.
The images of smiling faces taken just hours before the accident now stand in stark contrast to the grief that followed.
Along the Rio Grande river, where music and laughter had filled the evening air, there is now a quiet reminder of how quickly joy can turn to sorrow.
Six lives were lost in a matter of moments, leaving behind loved ones seeking answers and holding tightly to memories.
