bystanders, there's not the usual, and i think part of the reason is neighbors here are shocked, and we are hearing more details about those moments coming out after the shooting. in fact, we just got audio on a dispatch call of the moment the shooting happened, and those calls to 911. let's take a listen to those right now. >> tall white mail, short hair, light blue shirt, jeans. >> i got one. >> back in one right now? still alive. we have four down in the atrium.
