Details emerge about retired S.F. sergeant who killed wife, daughter

Key Points:

• Kevin Mannix, a retired San Francisco police sergeant who remained part-time with the department, is suspected of killing his wife Ann Mannix and their daughter before committing suicide in Marin County.
• Kevin was transferred from the staff services division, which handles background investigations, to the property division in early September, though the reason for the transfer is unclear and department officials have not commented.
• Ann Mannix, a retired deputy police chief and the first woman to lead the SFPD SWAT team, had returned to the department part-time after retirement, as had Kevin, who continued working as a background investigator until his death.
• Friends described Kevin as experiencing a late “midlife crisis” amid a painful divorce, with signs of trying to change his appearance, while Ann was emotionally healthy and planning a vacation despite the marital troubles.
• The shooting has prompted calls from San Francisco leaders for increased mental health support for police officers and first responders, including retirees, highlighting the need for better behavioral health resources within the department.
