Antonine Watson, who was found guilty of involuntary manslaughter for the 2021 killing of 84-year-old Vicha Ratanapakdee in San Francisco, will be released on probation after serving 5 years in prison. The judge sentenced Watson to 8 years total, but suspended the remaining 3 years as long as he adheres to the terms of his probation.

Why it matters

The killing of Vicha Ratanapakdee, an elderly Thai immigrant known affectionately as 'Grandpa Vicha,' sparked nationwide outrage and the 'Stop Asian Hate' movement. The decision to release Watson on probation after a relatively short sentence has raised concerns about accountability and justice for the victim's family.

The details

In January 2021, Antonine Watson, then 24 years old, attacked Vicha Ratanapakdee without provocation while the 84-year-old was on his daily walk in San Francisco. Watson shoved Ratanapakdee to the ground, causing him to hit his head. Ratanapakdee never regained consciousness and died from his injuries. Watson was initially charged with murder and elder abuse, but was ultimately found guilty only of involuntary manslaughter.

  • On January 28, 2021, Vicha Ratanapakdee was attacked and killed during his daily walk.
  • In January 2026, Antonine Watson was found guilty of involuntary manslaughter.
  • On March 26, 2026, the judge sentenced Watson to 8 years in prison, with the remaining 3 years suspended if he adheres to probation terms.
