In the videos, Mr Christian can be seen seated on a public MAX train while yelling about Muslims, Jews, circumcision, and "free speech", telling passengers that "if you don't like it, get the f*** out" before he slaps a mobile phone from Mr Namkai-Meche and yells "Do something, b****!"
Mr Namkai-Meche and Mr Fletcher stand to face Mr Christian, who shoves them away. Mr Fletcher shoves back, sending Mr Christian into a row of seats against the side of the train, and tells him to get off the train.
As Mr Namkai-Meche reaches for his phone from the floor, Mr Christian can be seen reaching for a knife, unleashing a quick, deadly attack within 12 seconds, as horrified passengers try to escape or look on without realising that Mr Christian was holding a knife.
He stabs Mr Fletcher in the neck, then stabs Mr Namkai-Meche several times, sending him backward as he grabs his neck. Mr Best is stabbed in the neck and face before falling to the floor of the train.
Passengers rushed to the victims to apply pressure to their wounds, to no avail, as the floor of the train filled with blood.
