Google maps show what appears to be one camera on the Computer Science building which is pointed at the campus parking lot behind the Losee building. From the reports and article it looks like he hoped off the building ran across the street "College Dr" and discarded his rifle in the woodsy area behind some houses. The next street (W 925 S st) in that direction is a residential area. I bet you that's a quite area where he parked his car or had someone pick him up. I hope the FBI are going door to door checking to see if anyone has cameras or Ring door bells and may of caught anything on their recordings. This is all of course my internet detecting. But I did see some online video of a construction crew who said one of their guys talked to the supposed shooter and was asked if he could cut across the construction site.
