SF West Portal Crash Sentencing (2026)

SF West Portal Crash Sentencing (2026) — An 80-year-old San Francisco driver who killed a family of four at a bus stop pleaded no contest and was indicated by the judge to face no prison time.

Summary

On March 19, 2024, Mary Fong Lau, then 78 years old, drove her Mercedes SUV at speeds reportedly reaching 70 miles per hour into a bus stop in San Francisco's West Portal neighborhood, killing a Brazilian couple and their two infant sons who were waiting for the Muni light-rail. The crash killed Diego Cardoso de Oliveira (40), Matilde Moncada Ramos Pinto (38), their one-year-old son Joaquim Ramos Pinto de Oliveira, and their three-month-old son Cauê Ramos Pinto de Oliveira.

Lau was charged in July 2024 with four counts of gross vehicular manslaughter. After initially pleading not guilty and seeking a reduction in charges in January 2026, Lau changed her plea to no contest on February 13, 2026. San Francisco Superior Court Judge Bruce Chan indicated during the hearing that, given Lau's age (80) and lack of prior criminal record, he was unlikely to sentence her to any prison time. Chan stated that Lau is "going to spend the rest of her days living with the knowledge of the harm she has caused to others," and expressed concern that a state prison term would likely be fatal to her.

Family members of the victims expressed profound disappointment. Denise Oliveira, sister of Diego Oliveira, addressed the judge, saying: "It feels like we have no rights. I feel deeply disrespected by this process. It doesn't feel like this is justice." The case drew widespread public attention and criticism of San Francisco's Superior Court, with observers arguing that the outcome reflected a pattern of leniency by the court's judges.
