A respected former police leader and her 24-year-old daughter have lost their lives in a devastating tragedy that has left their family, friends, and former colleagues in shock.
Ann Mannix, 65, was a retired deputy chief of the San Francisco Police Department who spent decades serving her community. Her daughter, Katherine “Katie” Mannix, 24, was studying nursing and had a future ahead of her.
Authorities say the two women were found dead alongside Ann’s estranged husband, Kevin Mannix, 68, a retired police sergeant, at a home in Marin County, California, on October 11, 2026. Investigators believe Kevin killed his wife and daughter before taking his own life. The investigation remains ongoing. 💔
Ann made history during her career, becoming the first woman to join the department’s SWAT team and later its leader before rising to the rank of deputy chief. Those who knew her remembered her as a courageous officer, a devoted mother, and someone who inspired others.
Katie was pursuing her dream of becoming a nurse. Her uncle described her as strong, independent, and outspoken, while family members are now struggling to comprehend the devastating loss.
The tragedy has left loved ones grieving three members of the same family. As tributes continue to emerge, Ann and Katie are being remembered not for the circumstances of their deaths, but for the lives they lived and the people they meant so much to. 🕊️
