3:10pm - NBC 4 says security video shows shooter entering building with a shotgun. Police believe he might have stolen a semi-automatic 9MM pistol from the first security guard he shot with the shotgun. He then might have shot another guard who would have responded carrying a AR-15 assault rifle, and then the shooter grabbed and used that. This is all speculative; what the media is reporting what the police are investigating.

3:10pm - DC Nationals cancel tonight’s game. Rescheduled for tomorrow afternoon.
