San Francisco Police Department Chief Derrick Lew this evening sent a department-wide email announcing, “with heavy hearts,” the deaths of SFPD veterans Kevin and Ann Mannix, a married couple. Kevin was a sergeant until 2018 and Ann retired as a deputy chief of the department in 2021.
Multiple outlets are reporting that Kevin Mannix shot and killed Ann in a murder-suicide that also claimed the couple’s youngest daughter, Katie. This corresponds with law-enforcement radio audio reviewed by Mission Local.
In that radio back-and-forth, law enforcement figures state that the “RP” — reporting party — says “the father killed the mother and the sister” with “six to nine shots” from a handgun. The alleged shooter was identified as Kevin Mannix.
Miguel Almaguer, the public information officer for the Marin County Sheriff’s Office, said that a 911 call was made shortly after 5 p.m. regarding shots fired in a home on the same small street in unincorporated Mill Valley where the Mannix family owns a home. The 911 caller had been within the home.
“Our deputies arrived on the scene within a few minutes and were able to reach the reporting party. She made her way outside of the property.”
Deputies entered the home and found three deceased people. Almaguer said deputies are presently awaiting a search warrant that would enable them to investigate further.

The Marin County sheriff and its coroner have not stated the circumstances of the shooting nor released the victims’ identities.
Kevin Mannix retired as a sergeant at Taraval Station in 2018. Ann Mannix was the first woman to make the SFPD SWAT team and the first woman to lead it — she is, to date, the only woman to ever serve on the SFPD SWAT team. The fourth-generation San Franciscan ascended to deputy chief overseeing special operations and retired in 2021.
“Please keep their family in your prayers,” reads Lew’s email.
