What happened in West Portal and the sentencing outcome
In March 2024, Mary Fong Lau, who was 80, drove into a bus shelter in West Portal at a frightening speed. She hit up to 70 mph before the crash, according to prosecutors.
The collision killed Diego Cardoso de Oliveira, 40, and his one-year-old son, Joaquim, on the spot. Matilde Moncada Ramos Pinto, 38, and her three-month-old, Cauê, died in the hospital a few days later.
Lau pleaded no contest. She gave up her right to a trial but didn’t admit guilt for sentencing purposes.
Judge Bruce Chan said he probably wouldn’t send Lau to prison. He pointed to her remorse and the fact that she’d lost her own husband in a crash decades ago.
The judge described Lau’s lifelong grief as a kind of punishment, though nothing like what the victims’ family faces. Lau’s attorney, Seth Morris, called her deeply remorseful and said she’d never be the same.
Lau told officers at the scene she didn’t know what happened and couldn’t stop before the crash.
The crash, plea, and sentencing
For readers in Marin, it’s worth noting that a plea of no contest counts as guilty at sentencing, even if the defendant doesn’t say the words. In Lau’s case, the court gave her two years of probation, 200 hours of community service, and took away her license—but no jail time.
The outcome split opinions among families and safety advocates. More than 8,000 people signed a petition asking for stricter penalties and better protection for pedestrians.
Family impact and community response
Relatives of the victims stepped up after the crash, pushing for changes to prevent this from happening again. Their petition called for more accountability and safer infrastructure at dangerous intersections.
This push for safety echoed in the redesign of the West Portal bus terminal.
Pedestrian safety reforms and the West Portal redesign
West Portal, a close-knit neighborhood on San Francisco’s edge, suddenly became the center of a citywide safety debate. After the crash, the city overhauled the bus terminal—adding barriers, a bike-share station, and clearer markings for people on foot.
City planners hoped these tweaks would make things safer for pedestrians, cyclists, and transit riders at this busy intersection.
New design features and ongoing concerns
The redesign is a real improvement, but safety advocates aren’t letting their guard down. The shock from this crash reached beyond city lines, sparking new questions about how places like Lombard Street and the Embarcadero handle pedestrian risks.
It’s something Marin County folks think about, too, since so many cross into the city every day.
Why Marin County residents should care
People in Marin—from San Rafael and Novato to Mill Valley and Sausalito—regularly cross the Golden Gate for work, appointments, or to see family. What happened at West Portal is a reminder that we all need safer streets, better speed controls, and real accountability for drivers who put pedestrians at risk.
Marin towns have already pushed for safer routes near schools, parks, and transit stops. This case just makes it that much clearer why those efforts matter across the Bay Area.
A call to action for Marin towns
Residents across Marin County can turn this news into real steps that protect people walking and biking in their own towns. Take a look at a few ideas that fit Marin’s unique communities, from Larkspur to Corte Madera and everywhere in between:
- Support safer street design near busy corridors and transit hubs in Mill Valley, Tiburon, and Sausalito. Focus on adding protected crossings and lowering speed limits where it matters most.
- Advocate for enforcement of speed limits on the roads connecting Marin to the city. This feels especially urgent near ferry terminals and bus stops in Larkspur and San Rafael.
- Promote public awareness campaigns about sharing the road with pedestrians, cyclists, and vulnerable users in Novato and Corte Madera. Honestly, a little more patience and understanding could go a long way.
- Push for rapid-response infrastructure improvements around schools and parks in San Anselmo and Ross. Maybe look at San Francisco’s post-crash redesigns for inspiration.
- Engage local leaders to fund safety programs and build protective barriers in parish corridors, shopping districts, and marina fronts from Sausalito to Point Reyes Station. Sometimes, it just takes a nudge to get things moving.
