It's now been two years since Alexandre Bissonnette walked into a mosque in Quebec City and opened fire.
He killed six people, and wounded five others, as 35 other worshippers including several children looked on in horror.
The next day Bissonnette told police he had attacked the mosque, because he was worried refugees would come to Quebec and kill his family.
And later we found out that his views on Muslims were heavily influenced by the far right in Canada and the United States.
And that he worshipped Donald Trump.
