Retired police sergeant kills officer wife and daughter before turning gun on himself at upscale Bay Area home
Three people found dead in a Bay Area home after what investigators believed to be a murder-suicide involving a retired police officer and his wife and adult daughter.
Kevin Mannix, 68, was found dead on Sunday evening in his family’s $2 million home in the Strawberry neighborhood of Mill Valley, California.
Sources told the San Francisco Chronicle that Mannix, a retired San Francisco sergeant, shot and killed his estranged wife, former SFPD Deputy Chief Ann Mannix, 65, and their youngest daughter, Katie, 24, before killing himself.
The Marin County Sheriff’s Office responded to reports of gunfire coming from inside the house shortly after 5pm on Sunday.
‘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.
Inside, deputies discovered three deceased individuals, identified as Kevin, Ann and Katie, and determined there was no ongoing threat.
‘The preliminary investigation indicates a suspected double-murder suicide involving three individuals. The suspected shooter is male,’ the sheriff’s office said.
Investigators have not shared any information about the circumstances leading up to the shooting, but detectives are processing the scene and their autopsies are scheduled for Tuesday.

Kevin Mannix worked for the San Francisco Police Department for 27 years before his retirement in 2018
San Francisco Police Chief Derrick Lew shared a message with the department announcing their deaths on Sunday, KGO reported.
‘It is with heavy hearts that we share the news of the passing of Ann and Kevin Mannix,’ Lew wrote.
‘Please keep their family in your prayers. BSU is available to all members who may need it during this difficult time.’
The San Francisco Police Officers Association issued a statement on Monday saying the ‘suspected murder-suicide has left our entire SFPD family 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 retired from 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.
The Daily Mail has contacted the Marin County Sheriff’s Office for more information.
