San Francisco Judge's Decision on Elderly Driver Sparks Outrage

2/15/2026, 3:46:54 AM

Fatal Incident and Legal Proceedings

Mary Fong Lau, an 80-year-old woman, has pleaded no contest to four counts of gross vehicular manslaughter after driving her Mercedes SUV into a family of four in San Francisco on March 16, 2024. The incident occurred as Diego Cardoso de Oliveira, his wife Matilde Ramos Pinto, and their two young children, Joaquim and Cauê, were waiting at a bus stop for transportation to the San Francisco Zoo. Lau's vehicle reportedly struck the family at speeds exceeding 70 mph, resulting in the immediate deaths of Diego and Joaquim, while Matilde and Cauê succumbed to their injuries days later.

Following her plea change from not guilty, San Francisco Superior Court Judge Bruce Chan indicated that he is unlikely to impose a prison sentence, citing Lau's age, lack of prior criminal history, and expressed remorse. He stated that sentencing her to prison would be akin to "sentencing her to die within the state prison system." Instead, he suggested a sentence of two to three years of probation and a prohibition on driving.

Community Response and Criticism

The decision has drawn significant backlash from the victims' family and the public. Denise Oliveira, sister of Diego Cardoso de Oliveira, expressed her feelings of disrespect towards the judicial process, stating, "It feels like we have no rights. I feel deeply disrespected by this process. It doesn’t feel like this is justice." Additionally, Assistant District Attorney Samantha Persaud voiced her objection to Lau's no-contest plea, advocating for home detention as a more appropriate sentence.

Victims' attorney James Quadra emphasized the need for moral accountability, arguing that Lau's actions were not a mere mistake but a serious crime. The family has also initiated a wrongful death lawsuit against Lau, alleging that she attempted to transfer and sell millions of dollars in assets to evade financial repercussions from the civil case.

Official Statements and Responses

Judge Chan acknowledged the incomprehensibility of the tragedy, noting Lau's emotional state during the proceedings. He remarked, "Mrs. Lau is going to spend the rest of her days living with the knowledge of the harm she has caused to others." The judge's tentative decision to impose a lighter sentence has been met with calls for more stringent consequences from both the victims' family and legal representatives.

What's Next

The court will confirm Lau's sentence in a separate hearing, where the final terms of her probation will be established. Meanwhile, the wrongful death lawsuit filed by the victims' family will continue, with allegations of Lau's asset transfers complicating the legal landscape.
