Philadelphia building collapses

Anybody been following this story? For example I notice:
"Attorneys from the Philadelphia firm Saltz, Mongeluzzi, Barrett & Bendesky stated that the newly released video of the collapse, caught by cameras mounted inside a passing city bus, proves that the excavator operator who has been the only person criminally charged in the case was not the sole individual responsible for the incident.

“Using the video to correlate a photo from across Market Street, it can be proven that the photo was taken 10 seconds after the collapse and it is clear that the excavator arm is pointed away from the wall that collapsed,” the statement reads. “This means it is highly unlikely that the excavator operator did strike the wall that collapsed.”"

The excavator operator has been charged with multiple counts of manslaughter.
