On Thursday, March 26, San Francisco Superior Court Judge Linda Colfax sentenced 24-year-old Antoine Watson — convicted in the death of 84-year-old Thai immigrant Vicha Ratanapakdee, known as Grandpa Vicha — to eight years. He was not sent to prison.
Colfax imposed the sentence but suspended it entirely. Watson received credit for five years of pretrial detention. The remainder was converted to probation. According to ABC7, conditions include weekly therapy sessions, search requirements, a stay-away order from the victim’s family and the attack site, and a requirement that Watson live with his mother in Hayward.
What Happened in 2021
On the morning of January 28, 2021, Vicha Ratanapakdee stepped out for his usual walk near his daughter’s home in San Francisco’s Anza Vista neighborhood. Surveillance footage shows Watson sprinting from roughly 50 yards away and slamming into the elderly man at full speed. Witnesses told The Voice of San Francisco they heard Watson shout something like “Why are you looking at me?” before the collision. Ratanapakdee’s head struck the pavement. He lost consciousness and died two days later from a traumatic brain injury.
Watson did not call 911 or render aid. He left the scene with his girlfriend. A neighbor who witnessed the attack called for help. Watson was arrested two days later.
The attack came at the height of a wave of violence against Asian Americans during the COVID-19 pandemic, when Asian residents were being blamed for spreading the virus. Ratanapakdee’s death became a defining moment for the Stop Asian Hate movement. A street in his neighborhood was named in his honor. A mural appeared in Chinatown.
The Verdict in January
The case stretched nearly five years. Watson remained in custody without bail throughout. In January 2026, a jury found him guilty of involuntary manslaughter and infliction of great bodily injury. He was acquitted of first- and second-degree murder and elder abuse.
The defense argued Watson was in emotional crisis the day of the attack — following a series of family arguments and a car breakdown the night before. His attorneys told the jury, according to KTVU, that the attack was impulsive, not planned. Prosecutors countered that Watson’s actions were deliberate: he was enraged over his broken-down car and chose a random victim. No hate crime charges were filed. Watson testified he had not registered the victim’s age or race.
Sentencing
Before announcing the sentence, Judge Colfax said she believed Watson’s conduct was rooted in trauma and PTSD, according to AsAmNews. She selected the great bodily injury count as the primary charge rather than involuntary manslaughter.
Watson addressed the court. He expressed remorse and apologized to the Ratanapakdee family, saying he had wanted to do so during trial but was advised against it by his attorney.
The victim’s son-in-law, Eric Lawson, asked the judge for the maximum sentence, describing Ratanapakdee as the person who held the family together.
Monthanus Ratanapakdee — Vicha’s daughter and the family’s public voice for five years — issued a statement after sentencing. According to ABC7, the family called the outcome deeply disappointing and said that when punishment fails to match the harm caused, it sends the wrong message about the protection of elderly people and public safety.
The Prosecutor’s Response
San Francisco District Attorney Brooke Jenkins said she understood the weight of the outcome for the family and the community, according to NBC Bay Area. She acknowledged that knowing Watson was walking free was difficult to absorb.
Five Years from Attack to Sentencing
Critics have focused on the timeline itself. Frank Noto of Stop Crime Action told The Voice of San Francisco that the prolonged proceedings amounted to a defense strategy: over five years, witness memories faded and Watson accumulated enough custody credits to effectively serve his time before sentencing. Under California rules in effect at the time, Watson earned two days of credit for every day in custody — totaling nearly a decade of credited time against a maximum four-year sentence for involuntary manslaughter.
Some observers have drawn a parallel to the 1982 Vincent Chin case, in which two Michigan autoworkers beat a Chinese American engineer to death and received probation with no prison time — a moment of rage, no hate crime charges, minimal punishment. The Voice of San Francisco was among outlets to note the comparison.
Watson’s attorney, Anita Nabha, emphasized her client’s difficult upbringing throughout the proceedings. According to KTVU, Watson spent five years in custody, much of it in isolation. The defense maintained the attack was an impulsive act, not a premeditated one.
Antoine Watson will serve out his probation and live with his mother in Hayward. The Grandpa Vicha mural in Chinatown may come down — the building’s owner has notified the family of plans to remove it, according to American Community Media.
