A BART police detective who fatally shot his supervisor during an apartment search in Dublin appears to have fired a single shot
after momentarily regarding his colleague as an armed threat, sources familiar with the investigation told The Chronicle on Saturday.
Investigators do not believe the shooting of Sgt. Tom "Tommy" Smith, BART's head of detectives, was the result of an accidental gun discharge, the sources said. Instead, they said, Tuesday's tragedy appears to represent a split-second misjudgment of a threat by another detective,
The sources said
the circular layout of the ground-floor, 723-square-foot apartment at the Park Sierra complex on Dougherty Road
appears to be a factor in the case.
The bathroom of the unit has two entrances - one connecting it to a laundry room near the front door and the other to a corridor at the rear of the bedroom with closets on both sides. Smith and Maes had separated during the search, sources said.
