So...before there was any shooting from the windows into the crowd,
Jesus knocked on the shooters door. Then..

he was hit by bullets through the door while on a private camera.
OR
he was chased down the hall and shot in the leg while trying to hide.
he called on his own phone to Hotel Authorities or on a hallway phone, or both. We still do not know.

The Shooter then began his carnage and crowd shooting six minutes later and stoop shooting 10 to 12 minutes later. There were thousands of rounds of ammunition left over. He could have kept shooting but didn't? Was he afraid of cops coming in and capturing him? Did he shot himself then? The cops did not arrive or even discover a wounded Jesus in the hallway for at least 45 minutes. Then they blew the door open and discovered the guns and ammo alongside the body of Poddard.
