Deputy Marshal buried; preliminary autopsy released

As a bugle played, Mary Fisher's flag draped casket was surrounded by family, friends and co-workers at the US Marshals Office.

Fisher was killed last Sunday at her home. Friends say she had been acting erratically. When police arrived at her home they say she started shooting at them, hitting one officer. That officer returned fire and killed Fisher.

U.S. Marshal David Jolley said Fisher was a great person. "She was a lieutenant in the National Guard and she was a person who had a very distinguished, long career in the U.S. Marshal service," he said. The events that happened the other night, we don't know exactly what happened there. That's not the person we knew."

The preliminary medical examiner report into Mary Fisher's death rules her death a homicide, saying Fisher suffered "multiple gunshot wounds" and her death was "violent".

Fisher was reportedly upset over a recent divorce. Investigators hope the complete autopsy will shed some light but Jolley was doubtful.

"It probably will never answer all of the questions in this situation," Jolley said. "I just don't know that it will ever answer all of the questions here."

Such as why a deputy U.S. Marshal would turn her gun on another law enforcement officer.
