Who was Kevin Mannix? Ex-San Francisco PD sergeant kills wife and daughter in shocking murder-suicide
Three members of a Marin County family found dead as investigation continues
Bharatmorningnews.com – A suspected murder-suicide inside a home near Mill Valley has left a former San Francisco Police Department deputy chief, her adult daughter and her retired police-sergeant husband dead, prompting an active investigation by Marin County authorities.
Deputy Chief Ann Mannix, 65, and her 24-year-old daughter, Katherine “Katie” Mannix, were found dead Sunday afternoon at the family residence on Strawberry Circle in the Strawberry neighborhood. Ann Mannix’s husband, retired SFPD Sgt. Kevin Mannix, 68, also died at the home.
Investigators believe Kevin Mannix fatally shot his wife and daughter before shooting himself. The deaths are being examined as a double murder-suicide involving members of the same family.
Deputies responded after gunfire call
Deputies were dispatched shortly after 5 p.m. following a 911 call about gunfire at the residence. The caller was able to get out of the house before law enforcement arrived.
Responding deputies discovered three people dead inside. Officials have said there is no continuing danger to the public, though detectives are still working to establish the circumstances that led to the shootings. No motive had been announced.
Property records identify the Strawberry Circle home as belonging to the two former officers. The location sits in Strawberry, a Marin County community near Mill Valley, north of San Francisco.
Long careers with the San Francisco Police Department
Kevin Mannix spent 27 years with the San Francisco Police Department before retiring in June 2018. His service included time at Taraval Station and other assignments within the department.
In a farewell message issued after his retirement, Mannix reflected on the relationships he formed during his career.
“I leave the SFPD, but I am taking your friendships with me forever.”
Ann Mannix had also built a career with the department and held the rank of deputy chief. The deaths have deeply affected former colleagues and the broader SFPD community, where both Ann and Kevin Mannix were known through years of service.
San Francisco Police Chief Derrick Lew called the incident especially hard to comprehend in light of the apparent circumstances. He offered condolences to the relatives, friends and colleagues grieving the loss.
Family friend recalls Ann Mannix’s optimism
Marie Hurabiell, a family friend and former congressional candidate, described the deaths of Ann Mannix and Katie Mannix as devastating. Hurabiell said Ann Mannix had recently been navigating a divorce and had spoken about the challenges that came with it.
“She acknowledged divorce was not fun or easy, but to have this happen right after she was so full of hope and joy and life,” Hurabiell said.
Her remarks underscored the personal loss felt by those close to the family, as investigators continue reviewing the events that unfolded at the home Sunday.
Police association mourns the loss
San Francisco’s Police Officer’s Association issued a statement expressing shock and grief over the deaths of Ann Mannix, Katie Mannix and Kevin Mannix. The organization said the news had shaken current and retired members of the department.
“It is with profound sadness, shock, and heavy hearts that we address the devastating news that emerged out of Marin County on Sunday evening. The tragic loss of retired Deputy Chief Ann Mannix, her daughter Katie, and retired Sergeant Kevin Mannix in a suspected murder-suicide has left our entire SFPD family reeling.”
The association also remembered Kevin Mannix’s lengthy service, noting that many officers had worked with him during his years at Taraval Station and elsewhere in the department.
“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.”
The investigation remains underway. Authorities have not released further details about the sequence of events or a possible motive, and the case continues to be treated as an isolated incident with no identified public threat.
