The man authorities say opened fire in a Buffalo grocery store Saturday, killing 10, appears to have left behind a white supremacist document centered on the idea of a plot to replace the White population with immigrants.

This far-right conspiracy theory, known as the “great replacement theory,” has inspired a lot of recent violence, including the 2019 Christchurch mosque shootings in New Zealand, where the shooter warned of “White genocide.” He later pleaded guilty to 51 murders, 40 attempted murders and engaging in a terrorist act.
