San Francisco police leader and daughter killed in suspected murder-suicide

A suspected murder-suicide involving a retired San Francisco Police Department leader has devastated the local law enforcement community. Retired Deputy Chief Ann Mannix, 65, and her 24-year-old daughter, Katherine, were killed at the family home near Mill Valley in Marin County. Authorities state that Ann’s husband, retired Sergeant Kevin Mannix, 68, allegedly shot both women before turning the gun on himself.

Ann Mannix was a prominent figure in the SFPD, notably serving as the first woman to lead the department’s SWAT team before overseeing the Field Operations and Special Operations bureaus. Following the tragedy, the San Francisco Police Officers Association canceled a planned memorial service, stating the family felt it was too soon to hold the event.

Rich Corriea, a retired San Francisco police commander and brother of Ann Mannix, attributed the violence to a long history of family trauma and mental health struggles involving Kevin Mannix. Corriea noted that Mannix’s youth was marked by instability, including the death of his father and his mother’s severe mental health issues, which led to him and his siblings being placed in orphanages.
