The Sacramento District Attorney's Office has filed murder charges on Friday against the man arrested for killing Sacramento police officer Tara O’Sullivan.
The felony charges facing gunman Adel Sambrano Ramos include a special circumstance of lying in wait and intentionally firing on O'Sullivan as she responded to a domestic disturbance at a north Sacramento home Wednesday evening.
The 26-year-old officer, a recent police academy graduate, was still in training. She is the first Sacramento city police officer to die in the line of duty in two decades.
Ramos is also charged with attempting to kill a second officer during the more than eight-hour standoff last week.
Ramos faces two counts of possessing two illegally modified, AR-15 style assault rifles. He is expected to be arraigned Monday afternoon in Sacramento County Superior Court.
