A former San Francisco police officer allegedly killed his wife, a former deputy police chief, and their daughter in a murder-suicide at a home in California’s Marin County.
Police responded to the Strawberry Circle home just after 5 p.m. local time on Sunday, Oct. 11, after receiving a report of shots fired, according to a Marin County Sheriff’s Office press release.
Officers found the bodies of Kevin Mannix, 68, his wife, Ann Mannix, 65, and their daughter, Katherine “Katie” Mannix, 24, inside the property. The caller was able to escape the residence.

“The preliminary investigation indicates a suspected double murder-suicide,” police confirmed, adding that the suspected shooter was male and that there was no ongoing threat.
According to ABC7, both husband and wife were former officers in the San Francisco Police Department.
Kevin was a former sergeant, while Ann had been a deputy chief, the outlet reported, adding that property records show the home was owned by the couple.
Friends and neighbors left flowers and tributes outside the home on Monday, Oct. 12, ABC7 reported, while Marie Hurabiell, a family friend, told the outlet she was “devastated” by Ann’s death.
She claimed that her friend had recently been going through a divorce from Kevin, but said she was “so full of hope and joy and life.”

In a statement, San Francisco Police Chief Derrick Lew called the incident “all the more difficult to process” given the nature of the deaths. He also paid tribute to Ann, who he said rose to the rank of deputy chief over 30 years of service and was the first woman to lead the department’s tactical company.

The investigation is set to continue, with autopsies scheduled for Tuesday, Oct. 13, police said. Police also noted that additional information may be released as it becomes available.
