Surveillance video from a SEPTA bus captures the moment of collapse, when a building under demolition crumbled on top of the Salvation Army thrift store at 22nd and Market Street in Center City. Two employees and four customers were killed during the June 5th collapse.

In the upper right hand corner of the video, you can see the collapse followed by plumes of smoke pouring into the street. Several people run away, but then stop in the street to look at what happened. Thirteen people were rescued from the rubble of the collapse.

As we get this first look at video of the collapse, city officials are in the middle of a third public hearing into the deadly collapse. City Council hoped to question Licenses & Inspections and officials with the Philadelphia Fire Department, but they've declined to testify with the investigation still ongoing. Kary R. Roberts, also known as Sean Benschop, is the only person charged in connection with the collapse.
