Gunman Behind Mormon Church Massacre Had Break Up with Church Member

A Michigan church massacre that left five worshippers dead is now being linked to the gunman’s bitter personal history—and chilling words uttered just days before the slaughter.

On September 28, 40-year-old Thomas Jacob Sanford rammed his GMC Sierra, draped with two American flags, through the doors of the Church of Jesus Christ of Latter-day Saints in Grand Blanc Township. He opened fire on parishioners and then set the building ablaze. Two victims were gunned down instantly. Three more perished in the flames.

Police stormed the scene and killed Sanford in a shootout within minutes. Grand Blanc’s police chief, William Renye, called it “pure evil” at a press conference. “This was an evil act of violence,” he said, confirming that all church members have since been accounted for.

What could drive a Marine veteran and father to such a monstrous act? According to accounts, Sanford’s hatred of the Mormon faith may have been fueled by a failed romance with a woman he met in Utah years ago.

Kris Johns, a Burton city council candidate, recalled a door-knocking encounter with Sanford just days before the massacre. “He was polite at first, even friendly,” Johns told the Detroit Free Press. “But then the conversation took a very sharp turn. Out of nowhere, he went off about the Mormons, calling the church the ‘antichrist.’ I just didn’t know what the next question was going to be.”

Sanford told Johns he had once dated a woman from a Mormon family while working out west plowing snow. He never elaborated, but his bitterness was unmistakable.

Sanford’s background makes the bloodshed even more baffling. A U.S. Marine who served in Iraq, he returned home to Burton, Michigan—a suburb of Flint with about 30,000 residents. Friends said he struggled with drug addiction after his deployment. He was married, and reports say he had a daughter battling serious health issues.

Social media accounts of his family, including his mother, showed unwavering support for President Donald Trump and Vice President JD Vance. A “Trump Vance” sign stood prominently in Sanford’s front yard on East Atherton Road, and as of Monday, reporters confirmed it was still there.

The massacre erupted in an America already roiled by headline-grabbing acts of violence—from the assassination of conservative activist Charlie Kirk earlier this year to the killing of two Catholics in Minnesota by a transgender shooter. These high-profile tragedies have sparked political blame games.

Some commentators were quick to claim Sanford was a leftist targeting Christians. But those who knew him insist the truth is more complicated. Johns says Sanford described himself as a Christian and claimed membership at Solid Rock Community Church, a small evangelical congregation eight miles north of the crime scene.

Sunday, coincidentally, was the final sermon for Solid Rock’s longtime pastor. “He never gave any indication he was planning this,” one church member told local media. “He just sat in the pews like everyone else.”

Authorities are calling the massacre a “targeted attack,” though they have not yet identified a clear motive. What’s clear is that a man who once wore the uniform of the U.S. military turned his fury against people of faith.

President Trump, who has made cracking down on domestic terrorism a priority of his second term, has not yet commented publicly on the massacre. But Michigan officials are bracing for tough questions about how Sanford slipped through the cracks.

“This was not political. This was not random,” Chief Renye said. “This was deeply personal—and deeply evil.”
