A trailblazing former San Francisco deputy police chief is dead, alongside her daughter in an apparent murder-suicide carried out by her husband, a retired police sergeant, according to the Marin County Sheriff’s Office.
Authorities have identified the deceased as Ann Mannix, 65, a former SWAT commander, her 24-year-old daughter, Katie, and her husband, 68-year-old retired San Francisco Police Sgt. Kevin Mannix.
“The preliminary investigation indicates a suspected double-murder suicide involving three individuals,” Miguel Almaguer, the Marin County Sheriff’s public information officer, said in a statement. “The suspected shooter is male.”
Speaking later at a news briefing, he specifically identified Kevin Mannix as the shooter and said he could not discuss any evidence found in the home.
