The man who opened fire at the Molson Coors plant Wednesday, killing five co-workers and himself, had been involved in a long-running dispute with a co-worker that boiled over before he came back with two guns and started shooting, according to law enforcement and brewery sources.
Anthony N. Ferrill, 51, had worked as an electrician for more than 20 years, about 17 of them at Molson Coors, according to multiple sources and online employment records.
A co-worker who asked not to be identified for fear of being disciplined said Ferrill believed he was being discriminated against because he was African American and that he frequently argued with at least one of the victims, a fellow electrician.
The co-worker said Ferrill often watched movies on his phone during the day, which the other electrician took issue with, and that the two accused each other of going into each others' offices and stealing tools or tampering with computer equipment.
About a year ago, the employee said, Ferrill started saying he believed brewery workers were coming into his home, bugging his computer and moving chairs around.
