Heartbroken family of three-month-old who died in tragic car accident that killed tot's parents and two-year-old brother donate his organs to save the lives of other children

The heartbroken family of the three-month-old who died in the tragic car accident in San Francisco have decided to donate his organs to help another baby.   

The baby, Cauê Ramos Pinto de Oliveira, died on Wednesday after he, his mother, his father and two-year-old brother were struck by an SUV that crashed into the West Portal Muni bus stop on Saturday.  

Diego Cardoso de Oliveira, 40, his wife, Matilde Ramos Pinto, 38, and their one-year-old son, Joaquin, were earlier pronounced dead following the incident.

Initially, Cauê survived and was placed in the UCSF Benioff Children's Hospital Pediatric Intensive Care Unit with severe injuries.

'Little Cauê was a fighter and our hero; his organs were donated and will serve to save the lives of other children,' the family said.

The family-of-four were waiting at the bus stop on Saturday while on their way to zoo when Mary Fong Lau, 78, struck them with her Mercedes SUV. 

Witnesses said that Joaquin went flying in the air from the impact of the crash. 

Matilde was taken to the hospital after the crash, while her husband and toddler died at the scene. She died on Sunday in the hospital. 

Lau was arrested Sunday on suspicion of vehicular manslaughter, driving the wrong way, driving at an unsafe speed and reckless driving. 

The driver was initially taken to the hospital for injuries and it remains unclear what caused her car to hop the curb, crash into a fire hydrant, pole and side of the local library. 

Some witnesses said Lau suffered a medical incident before the crash. Other said she got out of the car yelling 'What have I done?' Police have not released details on what led to the horror crash. 

Another witness, Nikki Mashburn, told The San Francisco Chronicle that she heard the crash and that is sounded like 'an explosion.' She said that the victims suffered head injuries.

'When the paramedics showed up, you could tell … they didn’t know what to do first,' Mashburn said.

'The stroller was clearly destroyed. Yeah, so he was still strapped in there,' Johanna Dimayuga, a resident in the area told CBS News.

The family lived in the Mission District, a neighborhood in the Bay Area, and planned to spend a day at the zoo together for Diego and Matilde's wedding anniversary, friends said.

The family referred to the late mother and father as real 'life enhancers' that 'everyone loves to be around'

Diego, a creative director at Apple, was from Brazil and Matilde was a film and advertising producer from Portugal.

Loved ones have been leaving tributes on the couple's social media accounts.

'So sorry this happened to you and your family. Rooting for your baby's health,' read one comment on Diego's Instagram.

Another said: 'My dear dear Matilde. I am so heartbroken. I cannot believe this you were and are an angel in my life forever. I miss you.'

San Francisco Mayor London Breed said on X, formerly Twitter, that she had visited the scene of the collision on Saturday. She called it 'heartbreaking.' 

The crash site has since been covered with stuffed animals, flowers, candles, and a stroller with a heart-shaped cutout that reads: : 'Remembering the precious lives lost on March 16, 2024.'

Advocates from Walk San Francisco added three pairs of shoes in honor of the mother, father and child who were tragically lost.

The advocacy group said that the incident was 'the most devastating pedestrian tragedies in our city’s history' and held a memorial for them on Monday at the crash site.

In a statement on Thursday, the family of the victim's said: 'We loved Diego, Matilde, Joaquim, and Cauê deeply and are sure the love they showed to their family and friends will serve as their legacy.' 

The family referred to the late mother and father as real 'life enhancers' that 'everyone loves to be around.' 

'The outpouring of love and grief from all over the world, which has greatly moved us, is a testament to this.' 

Following the tragedy, Walk San Francisco and locals have voiced their concerns about the intersection of Ulloa Street and West Portal Avenue where the bus stop is located.

The group noted that around the intersection, there are multiple places where families and children frequent, like a library, schools and train stations.

'It's time to fundamentally rethink areas like where this crash occurred, where thousands of people walk and cross and wait every day,' Jodie Medeiros, the executive director of the advocacy group said.

This was the second child killed in the city in less than a year, as deadly crashes like these have surged and left residents uneasy.
