San Francisco vigil marks two years since West Portal bus stop crash killed family of four
A public memorial returns to West Portal
A vigil in San Francisco’s West Portal neighborhood marked two years since a driver struck a transit shelter, killing a family of four that was waiting near the West Portal station area. The fatal crash occurred on March 16, 2024, when an SUV hit the bus stop, leaving three family members dead at the scene or shortly afterward and an infant critically injured. The infant later died, bringing the death toll to four.
The gathering came as the criminal case and related civil litigation continued to shape public attention around accountability and street-safety design at one of the city’s most complex transit junctions, where rail lines, buses, and vehicle traffic converge.
What is known about the victims and the crash
The people killed were Diego Cardoso de Oliveira, 40; Matilde Ramos Pinto, 38; their 1-year-old son, Joaquin; and their 3-month-old son, Caue Ramos Pinto de Oliveira. They were in West Portal on a weekend outing when the vehicle struck the shelter.
A San Francisco resident, Mary Fong Lau, was arrested after the collision. Prosecutors filed felony vehicular manslaughter charges, and the case proceeded through court filings and hearings over the following months. In February 2026, Lau changed her plea to no contest, a plea that permits sentencing without a trial while not requiring an admission of guilt.
How the case has progressed in court
The criminal case has drawn sustained scrutiny because it involves a fatal outcome in a setting primarily used by pedestrians and transit riders. Court proceedings have included dispute over charges and potential sentencing outcomes under California law for vehicular manslaughter cases that do not allege intent.
Separately, the victims’ relatives have pursued civil claims connected to the deaths. Court records and subsequent reporting have described litigation focused on damages and the defendant’s financial disclosures as the civil case moved forward alongside the criminal proceedings.
Safety responses at West Portal and the wider policy backdrop
The crash intensified debate over how San Francisco manages safety at busy transit nodes where drivers, pedestrians, and rail operations intersect. In 2024, city transportation officials discussed changes in and around West Portal intended to reduce conflicts and limit high-speed vehicle movements through the area.
By 2025, the transit agency had announced additional safety and public-realm upgrades at West Portal Station, including physical improvements aimed at organizing movements near stops and platforms.
The March 16, 2024 crash killed four members of one family at a West Portal bus stop.
The driver was arrested and later faced multiple felony vehicular manslaughter counts.
A no-contest plea entered in February 2026 set the case on a path toward sentencing without a trial.
Transportation changes and safety upgrades at West Portal have been advanced in the crash’s aftermath.
For families affected by traffic violence, anniversaries often function as both memorials and milestones in unresolved legal processes, with court schedules frequently stretching beyond the calendar date of the tragedy.
The anniversary vigil underscored how the West Portal deaths remain a reference point in San Francisco’s ongoing work to reduce severe traffic injuries and fatalities, particularly around transit stops where the most vulnerable street users regularly gather.
