did the shooting unfold?
On Saturday morning, worshippers had gathered at the synagogue, in the Squirrel Hill neighbourhood, for a baby naming ceremony during the Sabbath.
Squirrel Hill has one of the largest Jewish populations in Pennsylvania and this would have been the synagogue's busiest day of the week.
According to reports Mr Bowers, a white male, entered the building armed with an assault rifle and two pistols.
