Accused school shooter Ethan Crumbley collapsed last year while working at a local diner in an bizarre, unexplained incident captured on video. 

Footage, obtained exclusively by DailyMail.com, shows the 15-year-old stumbling into the back room of the 5-1 Diner in Oxford before falling to the ground.

The incident occurred  at 11am on September 20, 2020 as the boy had been filling in for another employee at the restaurant, where he'd worked on seven or eight other occasions, according to the owner. 

Video shows Ethan enter the room wobbly on his feet. He sways erratically from side to side while flailing his arms, then collapses and slams head-first into a cabinet.

He immediately struggles to stand up before stumbling a second time, as a co-worker comes to his aide. 

'Hold it, you alright?' the older male employee asks him. 'Yeah, I'm not feeling...' Ethan murmurs, almost unintelligibly. 

The owner told DailyMail.com that Ethan seemed embarrassed by the episode. The staff called his parents to come pick him up.

According to the owner, Ethan's mother blamed it on her son not eating that day. But the owner said she doubts that was the cause and wonders whether he may have been on medication or suffering from an underlying medical condition. 

'We sent him home,' the owner told DailyMail.com. 'The mom said it was just because he didn't eat anything. It seems a lot for that to just be not eating.'

Ethan's 18-year-old half-brother, Eli, also previously worked at the diner.

The owner recalled a separate concerning incident involving Eli last year. The owner described a day she smelled marijuana in a back room, and confronted Eli who had apparently been smoking. 

She told him she was going to call his parents, but said Eli wasn't concerned by the threat. She said he laughed and said his dad was the one who gave it to him.

'Where do you think I got it from?' he purportedly told the owner.

Eli and Ethan have the same father, but different mothers. Originally from Florida, the two boys later moved to Oxford with their dad James Crumbley and his second wife, Ethan's mom,
