A Hero’s Last Ride: Remembering Colden Kimber
The tragic death of Colden Kimber, a 28-year-old San Francisco resident, has sent shockwaves through his community and beyond. His final act, a selfless intervention to protect a stranger, has sparked an outpouring of grief, a criminal investigation, and a powerful testament to his character.
A Moment of Courage, a Life Cut Short
On July 26th, 2025, while waiting for the “K” train on Ocean Avenue with his girlfriend, Colden witnessed a man verbally accosting a mother and her children. Court documents detail the aggressor’s threatening behavior, filled with insults and intimidation. Without hesitation, Colden stepped in, positioning himself between the assailant and the terrified family. This act of bravery, a quiet yet profound display of selflessness, cost him his life. The attacker, identified as 29-year-old Sean Collins, launched a completely unprovoked attack, fatally stabbing Colden in the neck.
A Life Dedicated to Kindness
Colden wasn’t just a bystander; he was a vibrant member of the San Francisco community. A dedicated kinesiology student at San Francisco State University, a passionate cyclist, and a skilled hockey player, he was also employed at American Cyclery, where he was known for his positive spirit and unwavering kindness. His boss, Bradley Woehl, describes Colden as “irreplaceable,” highlighting his positive influence on colleagues and customers alike. The empty workbench where Colden meticulously repaired and built bikes stands as a poignant reminder of his absence. Friends like Reuben Sawyer echo this sentiment, expressing disbelief and profound sorrow at the loss of such a kind soul.
Justice Sought, Memories Cherished
The San Francisco District Attorney’s Office has charged Sean Collins with murder, with his arraignment scheduled for August 14th. While investigations continue, including a pending report on Collins’ mental health, the community rallies to honor Colden’s memory. Supervisor Chyanne Chen has confirmed close monitoring of the case by the San Francisco Police Department and SFMTA.

A Community Responds
The outpouring of support for Colden’s family is a testament to the profound impact he had on those who knew him. A GoFundMe campaign, organized by his mother, Lara Litchfield-Kimber, has already raised over $109,000 to cover memorial services and legal expenses. Lara herself speaks of her son’s inherent protectiveness, stating that his actions on that fateful day were perfectly in line with the man he was. Tributes pour in from friends, colleagues, and his cycling team, Dolce Vita Cycling, all painting a picture of a man whose kindness and selflessness were exceptional, even within the often self-focused world of amateur cycling. His mentoring of mechanics, coaching of racers, and support of fellow riders highlight his dedication to others.
A Legacy of Courage and Compassion
A memorial ride is planned for September 7th at the Polo Fields in Golden Gate Park, providing a space for the community to gather and remember Colden. His memory will live on not only through the stories shared by those who knew him but also through the unwavering commitment to justice and the powerful message of his selfless act. The image of Mount Colden in the Adirondacks, a favorite spot of Colden’s which suffered a recent mudslide, serves as a poignant symbol of both loss and enduring strength, mirroring the life and tragic end of a young man whose courage will not be forgotten. His legacy stands as a reminder of the extraordinary capacity for kindness and selflessness that resides within humanity.
