Note the added photos provided by the police don't appear to be very clear. Was any attempt made to increase clarity of the images?
It's difficult to believe there weren't any other surveillance/security cameras in the area which could have picked up more information - like, perhaps, pick up at least a partial identity of the license plate on the getaway car?
Most cameras are not clear enough to get plates, especially at night.
They have other video that has not been released as it bears on the investigation, and would not provide any additional assistance in identifying either the car or the perps. I have heard but have not seen myself, that video from inside a local club is on file, but due to lighting and noise is no better than the exterior views.
It’s a criminal investigation, everything doesn’t get released publicly.
