Sources told ABC7 that retired SFPD Sgt. Kevin Mannix shot and killed his wife, their daughter, and himself in Strawberry.

A source account of who fired is not a coroner's finding. ABC7, KTVU, Mission Local, and The Ark do not agree on the daughter's age, on whether the account includes a suicide, or on whether Ann Mannix was described as estranged. Until the sheriff or the coroner releases the names and the manner of death, the account of the shooting is what those newsrooms were told.

The Marin County Sheriff's Office account, as of Monday morning, stops at three deaths and an open investigation. KTVU, ABC7 San Francisco, and Mission Local reported that deputies responded just after 5 p.m. Sunday, Oct. 11, 2026, to a report of shots fired at a home on Strawberry Circle in Strawberry, an unincorporated community by Mill Valley, and found three people dead. The Ark and the Marin Independent Journal, citing the sheriff's office, put the 911 call at 5:03 p.m. The Independent Journal, in a story updated at 5:50 a.m. Monday, reported that deputies were met by the person who called 911, that the caller was uninjured, and that the office said there was "no known threat to the community." It printed the office's statement: "This investigation is in its very early stages. We are not releasing the identities of the deceased or additional information at this time." Almaguer, the sheriff's spokesman, told KTVU, ABC7, and The Ark that deputies found three deceased people and that who they were and how they were connected remained under investigation. The Ark reported he said there appeared to be no earlier calls for service at the address, that families had been notified, and that investigators were waiting Sunday night for a search warrant. KTVU's update at 8:11 a.m. Monday and ABC7's story timestamped Monday morning still said investigators were waiting on that warrant. A scene count is what the sheriff's office described. It is not a finding about who fired.

The names and the shooting sequence come from sources and from other newsrooms, and they do not match. ABC7 reported Monday that sources confirmed former San Francisco Police Sgt. Kevin Mannix was the suspect, and that his wife, Ann Mannix, a former deputy chief, was shot and killed along with the couple's 25-year-old daughter. Sources with intimate knowledge told ABC7's Dan Noyes that Kevin Mannix shot and killed his wife, then his daughter, before turning the gun on himself. ABC7 did not print the daughter's name. KTVU, updated Monday morning, reported that a source said the dead included former Deputy Chief Ann Mannix and her husband, former Sgt. Kevin Mannix, and that the third person was believed to be their 24-year-old daughter. KTVU reported the source said Kevin Mannix allegedly killed his wife and then his daughter. KTVU did not report that he then shot himself, and it reported that the sheriff had not publicly confirmed the account. Mission Local, updated at 1:03 a.m. Monday, reported that multiple outlets were describing a murder-suicide in which Kevin Mannix shot and killed Ann Mannix and the couple's youngest daughter, Katie. It reported that law-enforcement radio it reviewed had the reporting party saying "the father killed the mother and the sister" with "six to nine shots" from a handgun, and that the alleged shooter was identified on that traffic as Kevin Mannix. That radio line, as Mission Local printed it, does not say he then shot himself. The Ark reported that Kevin Mannix, 68, killed his estranged wife, retired Deputy Chief Ann Mannix, 65, and their daughter Katie, 24, before killing himself, according to multiple news outlets and sources close to the family. ABC7 and KTVU said wife. Only The Ark said estranged. The daughter's age is 25 at ABC7 and 24 at KTVU and The Ark. Only Mission Local and The Ark printed the name Katie. The sheriff and the coroner had not released those names or that sequence in any of these Monday accounts.

What is on paper, short of a coroner's release, is a chief's email and two careers. Mission Local reported that San Francisco Police Chief Derrick Lew sent a department-wide email Sunday night announcing, "with heavy hearts," the deaths of Kevin and Ann Mannix. The Ark reported it obtained that email, sent at 7:37 p.m., and quoted Lew: "It is with heavy hearts that we share the news of the passing of Ann and Kevin Mannix," and "Please keep their family in your prayers." KTVU reported that ABC7 had obtained a department memo from the chief naming the couple. The email announces deaths. It does not say who fired. The Ark reported Ann Mannix joined the San Francisco Police Department in 1986 and retired in 2021 as a deputy chief, then the department's highest-ranking woman. Mission Local reported she was the first woman to make the SFPD SWAT team and the first woman to lead it, and that she was, to date, the only woman to have served on it. The Ark reported she served on SWAT, became the first woman to command Northern Station, later led the tactical unit, and as deputy chief oversaw the Field Operations Bureau and then the Special Operations Bureau. KTVU, citing a police announcement, reported she was promoted to deputy chief in 2018 and served until she retired in 2021. Mission Local reported Kevin Mannix retired as a sergeant at Taraval Station in 2018. The Ark and KTVU reported he served 27 years and retired in June 2018. The Ark reported the couple's other daughter had been in the home, got out, and called 911. Mission Local reported the reporting party was a woman who had been inside and made her way outside, and it did not call her a daughter. She is not named here.
