Retired San Francisco Deputy Police Chief Ann Mannix and her daughter, Katherine “Katie” Mannix, are being remembered following their passing at the family’s home in Strawberry, Marin County, on October 11, 2026. Ann was sixty-five, and Katie was twenty-four. Ann’s husband, retired police Sergeant Kevin Mannix, sixty-eight, was also found deceased. Deputies responded shortly after 5 p.m. following emergency calls from the residence. Another person inside the home escaped and reached safety. Authorities described their preliminary findings as a suspected double homicide followed by suicide, identifying Kevin as the suspected person responsible. The investigation remained ongoing, with no continuing threat to the surrounding community reported.
Ann’s career included nearly thirty-five years with the San Francisco Police Department before her retirement in 2021. She became the first woman to join and later lead its SWAT team, eventually overseeing both the Field Operations and Special Operations bureaus. Colleagues remembered her leadership, integrity, and willingness to support other officers, particularly women developing their careers in the department. Her work also extended into community relationships and public safety initiatives. Tributes from police officials and city leaders emphasized the significance of her service and the barriers she helped overcome. For those who worked alongside her, her professional achievements were accompanied by a reputation for being approachable, capable, and generous with her experience.
Katie was pursuing nursing studies at the College of Marin, preparing for a career focused on helping others. Relatives and family friends remembered her warmth, playful personality, and ability to make people feel valued. Their recollections described a young woman whose future held plans of her own, beyond her family’s connection to law enforcement. Ann’s loved ones similarly spoke about the interests and relationships she enjoyed outside her career. Those memories help preserve a fuller picture of both women, recognizing their everyday kindness, ambitions, and connections rather than allowing the circumstances of their passing to define their lives.
