On October 12, 2026, retired San Francisco police sergeant Kevin Mannix, aged 68, killed his estranged wife Ann Mannix (former SFPD Deputy Chief, age 65) and their youngest daughter Katie (age 24) before taking his own life in their $2 million home in the Strawberry neighborhood of Mill Valley, California. Police responded to gunfire reports at around 5pm on Sunday and found all three deceased inside the house.

Autopsies on all three victims are scheduled for further investigation into the motives behind this tragic event.
