A SEPTA bus' surveillance video captures the moment when a building being prepared for demolition collapsed onto a Salvation Army thrift store at 22nd and Market Street in Philadelphia's Center City according to WCAU TV.

The video has already been viewed by investigators and is just now being made public.

In it the building can be seen coming straight down and vehicles at the intersection that were making a turn suddenly deciding to go straight and away from the area.

Six people died in the June 5 collapse. Smoke and dust quickly envelop the area as people run out of the thrift store and the bus comes to a stop.
