Three members of a family were found dead inside a Bay Area residence in what authorities are investigating as a suspected murder-suicide involving a retired police officer, his estranged wife and their adult daughter.
Kevin Mannix, 68, was discovered Sunday evening at the family’s home, valued at about $2 million, in the Strawberry neighborhood of Mill Valley, California.
Mannix, a former San Francisco police sergeant, is believed to have fatally shot his estranged wife, former SFPD Deputy Chief Ann Mannix, 65, and their youngest daughter, Katie, 24, before taking his own life, sources told the San Francisco Chronicle.
Deputies from the Marin County Sheriff’s Office were called to the property shortly after 5 p.m. Sunday after receiving reports of gunshots coming from inside the home.
‘Within minutes, deputies arrived on scene and made contact with the reporting party, who safely exited the residence. After securing a perimeter, deputies entered the home,’ the sheriff’s office said.
Authorities found three people dead inside and identified them as Kevin, Ann and Katie Mannix. Investigators said there was no continuing danger to the public.
‘The preliminary investigation indicates a suspected double-murder suicide involving three individuals. The suspected shooter is male,’ the sheriff’s office said.
Officials have not disclosed what may have led to the shooting. Detectives are examining the residence as part of the investigation, while autopsies for the Mannix family were scheduled for Tuesday.

The San Francisco Police Officers Association said Monday that the suspected murder-suicide had left the entire SFPD community ‘reeling.’
‘Ann Mannix was a trailblazer in our department – becoming the first woman to join and lead the SWAT team, and rising to lead both the Field Operations and Special Operations Bureaus,’ the association wrote on Facebook.
‘Many worked alongside Kevin during his 27 years of dedicated service at Taraval Station and beyond.
‘To see their lives, and the life of their 24-year-old daughter Katie, end in such a horrific and senseless manner is a burden that weighs heavily on every officer, active and retired.’
Kevin Mannix concluded his career with the SFPD in June 2018 after 27 years of service.

‘I am looking forward to a new life of leisure with family and friends. But I am a little saddened by the thought of not seeing all of you every day or at community events,’ he wrote in a letter to the Taraval Police Station at the time.
‘I will miss you all. Believe me, that is not a trite generalization… I leave the SFPD, but I am taking your friendships with me forever.’
Records show Ann served as deputy chief of the SFPD Field Operations Bureau in 2018, then led the Special Operations Bureau in 2019.
