A Sunday service in Grand Blanc, Michigan, turned into horror when a gunman drove a truck into The Church of Jesus Christ of Latter-day Saints, opened fire, and then set the building on fire.

Authorities confirmed four deaths, including two who died in the blaze. Eight others are hospitalized. The suspect, 40-year-old Thomas Jacob Sanford, was killed in a shootout with police.

The fire caused the chapel to partially collapse, leaving it a “total loss.” Investigators fear more victims could be in the rubble. The FBI and ATF are leading the case, calling it an “act of targeted violence.” The motive remains unclear, though officials are examining potential connections, including the recent death of LDS Church President Russell M. Nelson, who passed away at 101.

Governor Gretchen Whitmer expressed heartbreak, while LDS leaders urged, “We pray for peace and healing for all involved.” Faith leaders across religions voiced alarm over rising attacks on houses of worship.

Vigils are planned nationwide as the community mourns. Experts warn such violence threatens both lives and the sense of refuge that sacred spaces provide.
