Retired SFPD sergeant suspected in family murder-suicide

A retired San Francisco police sergeant is suspected of killing his wife and adult daughter before committing suicide at their home in Marin County on Sunday, October 11.

The victims have been identified as 65-year-old Ann Mannix, a former SFPD deputy chief and pioneering SWAT commander, 24-year-old daughter Katherine ‘Katie’ Mannix, and 68-year-old Kevin Mannix. Authorities responded to a 911 call reporting gunfire in the Strawberry neighborhood near Mill Valley. A resident inside the home managed to escape through a window and contact emergency services.

Ann Mannix was a prominent figure in the SFPD, recognized as a trailblazer for women in the department. Friends noted that she had been planning a divorce from Kevin, a retired sergeant who served 27 years with the force. While a motive has not yet been established, the incident has caused significant shock within the San Francisco Police Department and the local community.
