Authorities identify Mannix family deaths in Mill Valley shooting

Authorities identified three people found dead at a Mill Valley home after a suspected murder suicide involving a retired police sergeant, his former deputy chief wife, and their daughter, according to the Marin County Sheriff's Office. Deputies responded around 5 p.m. Sunday.

The victims were identified as Ann Mannix, 65, a former San Francisco deputy police chief, her 24-year-old daughter Katie, and retired San Francisco Police Sgt. Kevin Mannix, 68, according to the sheriff's office.

The Marin County Sheriff's Office said deputies entered the family residence after a caller escaped safely and found all three family members dead inside. Autopsies were scheduled for Tuesday.

"The preliminary investigation indicates a suspected double-murder suicide involving three individuals," said Miguel Almaguer, Marin County Sheriff's public information officer.

Almaguer later identified Kevin Mannix as the suspected shooter during a news briefing. He said authorities could not discuss evidence found inside the home.

"The suspected shooter is male." said Miguel Almaguer, Marin County Sheriff's public information officer.

The San Francisco Police Officers Association said the deaths affected the department community. The organization described Ann Mannix as a former leader with a notable career in law enforcement.

"It is with profound sadness, shock, and heavy hearts that we address the devastating news that emerged out of Marin County on Sunday evening," said Louis Wong, president of the San Francisco Police Officers Association.

Wong said Ann Mannix was the first woman to join and later lead the SWAT team. He also noted her involvement with youth sports and the city's Police Activities League board.

"Ann had a lot of talent, and she was very competent," said Lou Barberini, former San Francisco police officer and Bay Area columnist.

Barberini said Mannix was known as an athlete and police officer who was well-liked. San Francisco police did not immediately respond to a request for comment.
