Saturday 6:56PM. Frick Fine Arts Building and the Music Building.
First Saturday threat, first weekend threat. Are there really that many students in ANY building 7PM before Easter Sunday? (According to @OaklandZoo, both buildings close at 5PM. Good work.)
On the other hand, the last threat was almost exactly 24 hours ago.
Again, every data point puts the FBI and JTTF one step closer to catching him. This seems like a bad, bad play by the perp.
