The April 16, 2010 brick facade failure may have been caused by renovations and a lintel "removal" but I think a pre-tremor from the June 23, 2010 magnitude 5.0 earthquake was the culprit. Then a delay from the aftershocks ruptured a gas line and, boom, the fire starts. The figure in the video, shuffling along in black looks suspiciously like a Sasquatch (aka Bigfoot). We can only hope that Mulder and Scully get to the bottom of this case.
So much for that piece of the past, onwards and upwards, lets get on with the next demolition which coincidentally is next door at the old Sam the Record Man building.
Sam the Record Man has been demolished and construction is started on the new building.
