JUST IN: FBI Reveals Suspected Motive In Attack On Michigan Church

White House Press Secretary Karoline Leavitt revealed new details about the man who rammed his truck into a Mormon church in Michigan on Sunday, saying authorities have reached their first conclusions about what motivated him.

Thomas Sanford, a former Marine, was found dead after opening fire at the Church of Jesus Christ of Latter-day Saints in Michigan. He exchanged gunfire with police officers before being shot and killed.

Leavitt told Fox News on Monday that she has spoken with FBI Director Kash Patel, who said the Bureau has reason to believe that Sanford privately harbored a hatred against people of the Mormon faith.

“From what I understand, based on my conversations with the FBI director, all they know right now is this was an individual who hated people of the Mormon faith, and they are trying to understand more about this, how premeditated it was, how much planning went into it, whether he left a note, all of those questions have yet to be answered, but certainly will be answered by the FBI,” she said.

The FBI is currently executing a search warrant at Sanford’s home “to get to the bottom of why he would commit such an act of evil,” according to Leavitt.

The Trump aide added that Sanford’s family is cooperating with the FBI.

WATCH:

Authorities are expected to hold a press conference at 12:30 p.m. on Monday, where more details about the terrorist attack are expected to be shared.

The horrifying attack unfolded at the LDS church in Grand Blanc, where parishioners described cowering in fear as they waited to be shot.

Kristin Juarez became separated from her husband as the crack of gunshots caused the congregation to break apart and flee in all directions. She found herself barricaded in a bathroom, expecting to die.

“I thought, ‘If I have to die, it’s OK,’” Juarez, 54, said. “I feel good about where I am. And then I heard my husband’s voice, and he was calling for me.”

Brian Taylor, another churchgoer, said he and his wife first attempted to aid Sanford when he crashed into the church before realizing he was there to kill.

“We started rushing out to go help … and somebody yelled it was on purpose, I tried to get people out of the area and disperse away,” he said.

“I can confirm at this time that the FBI is now leading the investigation and is investigating this as an act of targeted violence,” Reuben Coleman, acting special agent in charge of the FBI Detroit Field Office, told Fox News on Sunday.
