Brendan Mannix remembered his Aunt Ann Mannix as a trailblazer who helped other women advance in the San Francisco Police Department, and his cousin Katie as an aspiring nurse who often sent loved ones messages of encouragement.<\/p>\n

He also tore into his uncle Kevin for the \u201csenseless act of violence\u201d that had left him \u201clost for words.\u201d<\/p>\n

\u201cMy beloved aunt, retired Deputy Chief Ann Mannix, and my dear cousin, Katie Mannix, lost their lives in a senseless act of violence. We\u2019re heartbroken, lost for words and forever changed,\u201d he wrote on Facebook.<\/p>\n

Katie Mannix was close to fulfilling one of her dreams, Brendan Mannix said.<\/p>\n

\u201cMy sweet Katie had her whole life ahead of her. She was so close to following in her older sister Lauren\u2019s footsteps and becoming a nurse,\u201d he wrote.<\/p>\n

\u201cKatie was the kind of person who would send you a random text just to say she loved you or to give you encouragement when you needed it. She had such a big heart and a way of making people feel special. It hurts knowing she won\u2019t get to live out the dreams she was so excited about.\u201d<\/p>\n

Brendan Mannix also reflected on his aunt\u2019s rise through the police department and her commitment to supporting the women who followed her.<\/p>\n

\u201cMy aunt Ann was a pioneer in the SFPD. She worked her way up to Deputy Chief, but she never forgot where she started. She looked out for the women coming up behind her and helped open doors for them. I\u2019m so proud of what she accomplished and the example she set,\u201d he wrote.<\/p>\n

Brendan Mannix, who also served as a San Francisco police officer, said working alongside relatives was \u201cone of the greatest honors of my life.\u201d<\/p>\n

\u201cI\u2019ll always treasure that,\u201d he added.<\/p>\n

He thanked police officers, friends and community members who had reached out to the family.<\/p>\n

\u201cYour love and support mean more than I can put into words,\u201d he wrote.<\/p>\n

Brendan asked supporters to keep his two surviving cousins in their prayers as the family grieves.<\/p>\n

\u201cMy heart is especially with my two surviving cousins. Please keep them and our family in your prayers,\u201d he wrote.<\/p>\n

\u201cI know I\u2019ll carry this loss for the rest of my life. Aunt Ann and Katie, I love you both and miss you more than I can say. I find comfort knowing our Lord and Savior is holding you in His arms, free from pain and suffering. Until we meet again.\u201d<\/p>\n

San Francisco police officers confirmed the deaths. Chief Derrick Lew wrote a department-wide message<\/a> saying the agency was sharing the news \u201cwith heavy hearts.\u201d<\/p>\n

Chief Lew added: \u201cPlease keep their family in your prayers. BSU is available to all members who may need it during this difficult time.\u201d<\/p>\n

A close family friend, who said she was Ann Mannix\u2019s best friend of 60 years, also confirmed the deaths to The California Post, adding: \u201cThis is so sad for me. She was my best friend of 60 years. Love her, she didn\u2019t deserve this.\u201d<\/p>\n

Brendan Mannix also served as a SF police officer alongside his aunt, saying it was one of the \u201chonors of my life.\u201d Facebook\/@brendan.b.mannix<\/p>\n

Deputies who responded to the scene after 5 p.m. found all three dead inside the home.<\/p>\n

Shots were fired in the Strawberry Circle neighborhood, which is an unincorporated area of Strawberry east of Mill Valley, according to a news release.<\/p>\n

Police arrived within minutes to the home and reached out to the person who made the initial call. That person had left the home, according to the sheriff\u2019s office.<\/p>\n

The perimeter around the residence was secured for further investigation. Detectives with the sheriff\u2019s office investigations unit were still at the scene Sunday night.<\/p>\n

\u201cThere is no known threat to the community,\u201d they said, according to the San Francisco Chronicle.<\/p>\n

Ann Mannix climbed the ranks of the San Francisco Police Department, becoming deputy chief of the Field Operations Bureau in 2018 before taking charge of the Special Operations Bureau in 2019, according to department records<\/a>.<\/p>\n

She also made history as the first woman to serve on the department\u2019s SWAT team and eventually lead the unit.<\/p>\n

Her husband Kevin Mannix retired from the SFPD in June 2018 after serving 27 years on the force.<\/p>\n

A close family member who spoke with The California Post confirmed that the relationship between Ann and Kevin was \u201cnot great\u201d and that the two had their difficulties, but didn\u2019t foresee this happening.\u00a0<\/p>\n

They also said that to their understanding, the two were not estranged.\u00a0<\/p>\n

In a farewell letter<\/a> published by Taraval Station following Kevin Mannix\u2019s retirement, he looked back on the friendships he had built throughout his career and expressed his desire to spend more time with loved ones.<\/p>\n

\u201cI leave the SFPD, but I am taking your friendships with me forever,\u201d he wrote.<\/p>\n

After the shooting Sunday night, San Francisco\u2019s Police Officer\u2019s Association said in a statement: \u201cIt is with profound sadness, shock, and heavy hearts that we address the devastating news that emerged out of Marin County on Sunday evening.<\/p>\n

\u201cThe 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.<\/p>\n

\u201cThere are no words that can fully capture the depth of this tragedy, nor are there simple answers to the painful questions we are all asking.<\/p>\n

\u201cAnn Mannix was a trailblazer in our department\u2014becoming the first woman to join and lead the SWAT team, and rising to lead both the Field Operations and Special Operations Bureaus.<\/p>\n

\u201cMany 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.\u201d<\/p>\n

San Francisco Mayor Daniel Lurie<\/a> said: \u201cI am deeply saddened by the tragic deaths of retired SFPD Deputy Chief Ann Mannix and her daughter, Katie.<\/p>\n

\u201cDeputy Chief Mannix dedicated decades of her life to serving San Francisco. She was a trailblazer in the police department, becoming the first woman to join and lead the SWAT team and rising to lead both the Field Operations and Special Operations Bureaus.\u201d<\/p>\n
