Tragic Discovery on Strawberry Circle

Details of the Marin County Incident

Deputies from the Marin County Sheriff’s Office rushed to a residence located on Strawberry Circle on Sunday evening following a 911 call regarding shots fired. Fortunately, one individual managed to safely escape the home prior to law enforcement establishing a secure perimeter and entering the dwelling.

Upon entry, deputies sadly found three individuals deceased from apparent gunshot wounds. Investigators have noted that there were never any prior calls for service registered to this specific residential address before this shocking event took place.

Victims Identified as Retired SFPD Veterans

The San Francisco Police Officers Association formally identified the deceased individuals as retired Deputy Chief Ann Mannix, 65, her husband, retired Sergeant Kevin Mannix, 68, and their 24-year-old daughter, Katie. Initial reporting and internal sources indicate that Kevin Mannix carried out the attack before taking his own life, though an official determination is pending.

While the exact motive remains under active investigation by local authorities, the community continues to process the heavy emotional toll of the tragedy. Exploring local resources or planning a stay nearby often brings travelers to Mill Valley hotels, where community safety and well-being are always deeply valued.

Remembering the Mannix Family Legacy

Ann Mannix’s Trailblazing Career

Ann Mannix was widely remembered as a true departmental trailblazer who dedicated over 30 years of her life to law enforcement service. She made history within the department by becoming the first woman to ever lead the SFPD tactical company before officially retiring in 2021.

Her husband, Kevin Mannix, had also previously retired from the police department in June 2018 following a commendable 27-year career protecting the public. Their sudden passing has prompted an outpouring of grief and condolences from law enforcement associations and community members alike.

Ongoing Investigation and Community Impact

The Marin County Sheriff’s Department continues to investigate the underlying factors that led to this unprecedented domestic tragedy. Officials are urging anyone affected by domestic or mental health crises to utilize available support networks and confidential helplines for assistance.

As the neighborhood comes to terms with the loss, local officials emphasize the importance of community support during difficult times. Those looking to understand more about the region or seeking out things to do are encouraged to respect local privacy as the healing process slowly begins.
