PFLUGERVILLE — At 12:56 p.m., a single shot rings out at Windermere Elementary School.
A second later, a few more rounds pop off, their harsh blasts echoing off the main hallway’s high ceilings. Then, the screams begin. Nearly two dozen people stream out toward the main exit, their hands up, running toward safety. A man and woman stand at the end of the hallway, navigating slowly through the oncoming pack. But before they reach the source of the shots, before they peer around the hallway’s blind corner, out steps a man with a gun, his barrel pointed high at those fleeing.
