Kevin Mannix and Ann Mannix Death, Obituary: Retired San Francisco Police Couple and Daughter Reported Killed in Marin County Shooting

The San Francisco law enforcement community is mourning the reported deaths of retired police sergeant Kevin Mannix, his wife, Ann Mannix, a retired deputy chief, and their daughter following a shooting at a residence in Marin County, California, on Sunday, October 11, 2026.

According to local media reports, three people were found dead inside a home on Strawberry Circle in the unincorporated Strawberry area near Mill Valley. Reports citing sources familiar with the investigation identified Kevin and Ann Mannix among the victims and identified the third victim as their youngest daughter, Katie. Authorities had not publicly confirmed all victim identities or released a complete account of the circumstances in the initial reports.

The Marin County Sheriff’s Office received a 911 call shortly after 5 p.m. reporting gunfire inside the residence. Deputies arrived within minutes and contacted the reporting party, who had safely exited the home. After establishing a perimeter, deputies entered and discovered three deceased individuals.

Local reporting, citing law-enforcement radio communications and investigative sources, alleged that Kevin Mannix shot his wife and daughter before dying in a murder-suicide. However, the sheriff’s office had not publicly released a complete official account of the shooting, and the investigation remained ongoing.

Kevin Mannix served with the San Francisco Police Department for 27 years, retiring as a sergeant at Taraval Station in June 2018. In his retirement message, he reflected on the friendships he had built throughout his career and his plans to spend more time with family and friends.

Ann Mannix retired in 2021 as a deputy chief after a distinguished career with the department. She was known for her work in specialized policing and was reported to be the first woman to join and lead the SFPD SWAT team. She later held senior leadership responsibilities within the department’s operations divisions.

San Francisco Police Chief Derrick Lew reportedly informed department personnel of the couple’s deaths in an email expressing deep sorrow and asking colleagues to keep the family in their thoughts and prayers.

The deaths have deeply affected colleagues and members of the wider law enforcement community, who are awaiting further confirmed information about the tragedy.
