The Michigan shooter seems to have hated Mormons, called them the Antichrist.

[Ocelot II]

A city council candidate had a conversation with him about a week before the shooting.

He said Sanford began asking him open-ended questions about Mormonism, first asking how Johns felt about the religion. And the more questions Sanford asked on the topic, the more pointed they became, Johns said. He said Sanford asked him about the Mormon bible, the role Jesus plays in the religion, the history of the LDS church and Joseph Smith Jr., the founder of Mormonism and the LDS movement.

But Johns said everything Sanford asked him about Mormonism led to Sanford declaring the religion as "the antichrist.". . . .

Johns said Sanford told him he moved to Utah at one point to plow snow and had a relationship with a woman there whose family was Mormon.
