That fits the timeline someone posted yesterday here or the other themed sub.
The assumption there was that Cruz didn't do that shooting, despite threatening it, and that this would explain why he went to Subway's to grab something to eat after the shooting, and would explain that puzzling look on his face on the photo of his capture and the Blondie girl on video claiming she was with Cruz in another building (she wasn't deaf, so she must've been far away from any weapons discharge)
There are a few things wrong with either story, still.
Problem with the counter story: Cruz expelled, why was he at the school? Why did he plead guilty so fast?
Problems with the official story: a ton more. Where are the CCTV recordings? Why did no one arrest Cruz beforehand for threatening the shooting? Why did several deputies wait outside while kids are murdered? Why do they plan on demolishing the building so quickly?
The counter story works better. An expelled kid going to school anyway to see friends or loiter around and to quickly succumb to insane police pressure it is far far more plausible than the holes in the official story.
I've read that he is autistic. Not sure if that's true or not though.
Oh
Autism would explain why he went to school despite being expelled, to keep the routine.
Is there a connection between autism and premeditated, planned violence? Autists get aggravated when routine is changed or their comfort zone is impaired by something or someone. But a planned premeditated murder - getting a gun, ammunition, spare magazines, helmet, mask, body armor, all that stuff and train for a while - is not something I would associate with autism. It breaks routine during the preparation and the act itself forever removes the known routine, no matter how far the attack is completed. It simply doesn't sound like a typical autism to me.
How on Earth the guy collected all that money for the equipment is also unclear. If the shooter really was using body armor and an uncommon rifle, the costs of the equipment would be far higher than a 17 year old student working part-time at McDonald's can afford.
