Her husband, a retired police sergeant, is suspected of killing both before taking his own life.
A suspected double murder-suicide in California has claimed the lives of former San Francisco Police Department Deputy Chief Ann Mannix, 65, and her daughter Katherine “Katie” Mannix, 24.

Police responded to a 911 call reporting gunfire at the residence shortly after 5 pm. The caller managed to escape the house before officers arrived. Deputies subsequently discovered three people dead inside the property.
