LANSING, Mich. (AP) — The former Marine who opened fire in a Michigan church and set it ablaze last month was motivated by “anti-religious beliefs” against The Church of Jesus Christ of Latter-day Saints, the FBI confirmed Friday.

While friends of the gunman in the deadly shooting have said he harbored hatred for what is widely known as the Mormon church, the FBI had previously declined to specify the motivation behind the attack that left four people dead and the church burned to the ground, except to say it was a “targeted” act of violence.

The gunman, Thomas Jacob Sanford, 40, was killed by law enforcement responding to the shooting.

“I am confirming this is a targeted act of violence believed to be motivated by the assailant’s anti-religious beliefs against the Mormon religious community,” Jennifer Runyan, special agent in charge of the FBI Detroit field office, said in a prerecorded video message. The agency declined to share further information on what led to its conclusion.

Sanford drove his pickup truck into the side of a Latter-day Saints chapel in Grand Blanc Township, 60 miles (80 kilometers) northwest of Detroit, on Sunday, Sept. 28, and began shooting at congregants. Authorities have said he used gasoline as an accelerant to then light the church on fire.

The FBI said Friday that nine people were injured in the attack. The previous official count had been eight.

“During our investigation, an additional individual was determined to be “injured” during the Grand Blanc critical incident,” a spokesperson said in a statement.

The agency declined to comment Friday on the nature of the additional injury.

The four people who were killed have been identified through family and friends as Craig Hayden, William “Pat” Howard, John Bond and Thelma Armstrong.

Lisa Louis, who was in the chapel when her father, Hayden, was fatally shot, wrote in a letter that after looking into the shooter’s eyes, she forgave him, “with my heart.”

Earlier this month, top church leaders preached a message of love and forgiveness in the wake of the attack while gathered for the faith’s twice-annual general conference in its home state of Utah. Its members responded by raising hundreds of thousands of dollars in an online fundraiser for the gunman’s family.

The church said it strengthened its security protocols for the conference and, days later, for the funeral of its oldest-ever president, who died a day before the Michigan shooting.

The Church of Jesus Christ of Latter-day Saints did not have a comment Friday.

Brandt Malone, a member of the faith who was attending services at a nearby church on the morning of the shooting, said the FBI’s statement “did confirm some of our darkest fears — that this attack was motivated by hatred.”

“This affects all believers of all religious traditions, and it hurts that there are those out there who are motivated by the darkest of feelings,” he said.

Malone grew up attending events at the church where the attack occurred. He said local Latter-day Saints have been uplifted by an outpouring of love from the Grand Blanc Township community and other religious congregations.

Authorities have released little information about Sanford and the attack. People who knew him have said he began vocalizing anti-Mormon sentiments years ago after living in Utah, where he dated and broke up with a girlfriend who was a member of the faith. Sanford had moved to Utah after leaving the Marines and told his friends he had become addicted to methamphetamines.

An attorney acting as a spokesperson for Sanford’s family did not immediately return a request for comment.

Hundreds of residents from Grand Blanc gathered at a high school football field Tuesday night for a vigil honoring those affected by last month’s shooting at a local Church of Jesus Christ of Latter-day Saints. That attack left 5 people dead, including the shooter, and 8 others injured.

A number of religious and civic leaders took to the podium during the hour-long event, which was filled with prayers for victims and appreciation for local first responders. Grand Blanc Township supervisor Scott Bennett calls the attack a defining moment.

“And we want the families,” says Bennett, “and the world to know that Grand Blanc will not be defined by this horrific act of violence.”

Local law enforcement at the vigil could not provide an update on the ongoing investigation into the shooting, which is being led by the FBI. It’s been more than a week since the attack, but the bureau has not yet shared a motive or an official victim list.

Details on what happened between when the attack began and when first responders arrived have also not been made public. Local residents have told WDET that the alleged gunman held anti-Mormon sentiments.

Grand Blanc superintendent of schools, Trevor Alward, says the event’s impact has been felt across the community.

“We take back Grand Blanc by renouncing this act and celebrating our resilience. We are a community that is resilient. We are a community that shows love and compassion for each other.”

An official fund to support the victims of the attack can be found on Grand Blanc Township’s website. A separate go-fund-me page started by members of the Latter-day Saints community has raised more than $380,000 in support of the shooter’s family.

On Sunday morning, a gunman rammed a pickup truck decorated with American flags into the Church of Jesus Christ of Latter-day Saints in Grand Blanc. He opened fire on the Mormon congregation and burned down the building.

5 people, including the shooter, are dead. The FBI says it’s still investigating a motive.

Kris Johns is a Burton, Michigan resident running for a seat on his local city council. He had an interaction with the suspect, 40-year-old Thomas Jacob Sanford, just days before the attack while canvasing houses ahead of the November election.

Johns says he didn’t realize that the man he spoke with was the suspect, until he saw photos of Sanford after the shooting.

“I do not remember him giving his name,” says Johns, “so the Sanford name I did not connect.”

He says Sanford came across as warm and genuine at first but adds that his line of questioning quickly shifted to questions about the Mormon religion. By the end of the conversation, Johns says Sanford told him he thought Mormons were the Anti-Christ.

“I’ve seen people more animated and angry about football teams,” says Johns. “His behavior, and this is 100% speculative, was indicative that he’s felt about this for a long time.”

Johns says he felt many of Sanford’s views seemed to be formed during a time he lived in Utah.

Anyone who has information that could help the FBI in their investigation is encouraged to reach out to the Bureau at their online tip portal or call 1-800-CALL-FBI (1-800-225-5324).

At least five people, including the attacker, are dead after a gunman opened fire inside the Church of Jesus Christ of Latter Day Saints in Grand Blanc on Sunday morning. Eight others were taken to the hospital.

The shooter has been identified as 40-year-old Thomas Jacob Sanford, a military veteran from Burton, Michigan. Authorities say he rammed his truck into the church just before 10:30 a.m. local time and opened fire on the Mormon congregation.

The church was also set on fire during the ordeal. Investigators believe Sanford intentionally started the blaze and likely used an accelerant to intensify the flames.

Grand Blanc Township police chief William Renye, says local authorities were on the scene within minutes.

“The suspect,” says Renye, “was neutralized at 10:33:44 a.m. in the parking lot of that church.”

The FBI is leading an investigation into the attack and is treating it as a targeted act of violence. State law enforcement say they’ve responded to a number of bomb threats in the community following the Grand Blanc attack.

When asked whether the attack on the Mormon church was retaliation for the shooting of Charlie Kirk in Utah, Michigan State Police lieutenant Kimberly Vetter says it’s too soon to pinpoint a motive.

“That’s exactly what it is,” says Vetter, “is speculation. And we won’t come to those types of conclusions for some time.”

Law enforcement say they have not yet determined whether there are additional bodies in the burned-out church.

The FBI is asking members of the public to share any information that may help with the investigation.  That can be done by calling 1-800-CALL-FBI (1-800-225-5324) or by using the Bureau’s online tip portal.
