TLDR
California driver Mary Fong Lau received probation, not prison, after pleading no contest in a crash that killed a family of four at a San Francisco bus stop; relatives are also pursuing a wrongful death lawsuit that alleges concealed assets.
As an 80-year-old driver, Mary Fong Lau admitted responsibility in criminal court for the San Francisco bus stop crash that killed Diego Cardoso de Oliveira, his partner, and their two children. The judge imposed probation and a license suspension instead of incarceration. The victims’ relatives argue that the outcome does not reflect the scale of their loss.
Fatal Bus Stop Crash
According to Law & Crime and local coverage, the Brazilian couple and their young children were waiting at a bus stop near the West Portal Muni station on their way to the San Francisco Zoo when Lau’s Mercedes SUV left the roadway on March 16th, 2024. Prosecutors said the vehicle was traveling about 70 mph through a residential area before striking the family.
Oliveira, 40, his partner, 38-year-old Matilde Moncado Ramos Pinto, and their infant and toddler were all pronounced dead. Oliveira’s sister later told KRON, a CW affiliate, that “Diego and his family were simply going to the zoo on a Sunday morning, celebrating their anniversary,” adding that the legal consequences were not a match for what was lost.
Contrasting Accounts of What Happened
Immediately after the crash, Lau reportedly told a witness she tried to brake but hit the accelerator instead, according to reporting by the San Francisco Chronicle that cited court documents. In a subsequent interview with police at Zuckerberg San Francisco General Hospital, she gave a different account of a sudden mechanical problem that allegedly caused the SUV to surge forward.
The Chronicle reported that Lau claimed a malfunction caused the vehicle to accelerate rapidly and that she could not slow it despite attempts to brake and shift into park. Public reporting does not describe investigators confirming any defect, and prosecutors continued to pursue four counts of vehicular manslaughter rather than shifting focus to an alleged mechanical failure.
Sentencing, Civil Case, and Unresolved Anger
Lau pleaded no contest to four felony counts of vehicular manslaughter. At sentencing, San Francisco Superior Court Judge Bruce Chan ordered two years of probation and a three-year driver’s license suspension, citing Lau’s age, lack of criminal record, and expressions of remorse as key factors in not imposing jail or prison time, according to KRON.
Family members of the victims told ABC affiliate KGO they opposed efforts to reduce the charges and believed the conduct amounted to gross negligence. Ramos Pinto’s brother said, “We’re vehemently against them, because no evidence has been provided that would suggest this isn’t gross negligence,” and called for Lau to be held fully accountable. Relatives have also filed a wrongful death lawsuit, and KTVU reported that the complaint accuses Lau of moving or concealing assets to keep them out of reach of any judgment.
The criminal case against Lau is now resolved, with no incarceration ordered, while the wrongful death suit continues in civil court. The legal conclusion in one forum, and the possibility of further findings in another, leave a gap between what the system has imposed and what the victims’ families say would feel like justice.
