Sept. 29 (UPI) — Authorities are no longer looking for victims in the shooting at a Michigan church that left four dead and eight injured.

The dead gunman, Thomas Jacob Sanford, a 40-year-old Marine who served in the Iraq War, described Mormons as “the antichrist” to a Burton City Council candidate about one week before the shooting.

During a news conference Monday, Grand Blanc Township Police Chief Bill Renye said authorities have accounted for anyone who attended services Sunday morning at the Church of Jesus Christ of Latter-Day Saints about 50 miles north of Ann Arbor.

Sanford, 40, of Burton, Mich., drove a vehicle into the building at about 10:25 a.m. EDT Sunday and opened fire with an assault-type weapon, local police said. Sanford was shot dead in the church’s back parking lot by two police officers.

“We still are in the process of clearing out that church, but at this time, everyone is accounted for,” Renye told reporters.

The injured, who ranged from 6 to 78 years old, were taken to Henry Ford Genesys, and two of them are still in critical condition, according to Dr. Michael Danic, chief of staff at the hospital in Grand Blanc.

Five were treated for wounds, including the person who died, and three others were treated for smoke inhalation, with one still intubated, Danic said. A 6-year-old child was stabilized and released, Danic said.

Police said 10 were injured and two later died.

Danic said several of the hospital’s resident physicians were at the church during the service, describing them as “heroes.”

“Not only were they victims, they are also first responders,” Danic said. “And having your friends and family come in injured and take care of them is a really incredible experience.”

The FBI, which is the lead agency in the investigation, has interviewed more than 100 victims and witnesses, Reuben Coleman, acting special agent in charge of the FBI’s Detroit field office, said.

“The FBI is investigating this as an act of targeted violence, and we are continuing to work to determine a motive,” Coleman said at the news conference.

The Bureau of Alcohol, Tobacco, Firearms and Explosives dispatced a “world-renowned” specialized rapid response team to investigate, ATF acting special agent in charge James Deir said at the news conference. Team members arrived Sunday night.

“They have been used all over the world, and they come from places as far as California, Hawaii, and they’re here in Michigan now,” Deir said.

Improvised explosive devices were found but investigators are still trying to determine a motive.

“Our special agents, victim specialists, child advocates, forensic interviewers and local partners have interviewed over 100 victims and witnesses to date, and are continuing to interview individuals as we speak,” Coleman said.

The suspect is believed to have ignited the church with gasoline.

“This is not Grand Blanc. This does not define Grand Blanc and who we are,” Renye said during a news conference. “We are a community, and I am confident that together we’re going to build a stronger community due to this incident.”

Gov. Gretchen Whitmer also spoke at the news conference.

“We’ve seen gun violence in our schools, stores, parades, festivals and our houses of worship,” she said. “These are places that we go to feel connected, to feel safe, to be together.

“But today, this place has been shattered by bullets and broken glass. And this might be a familiar pain, but it hurts all the same every time.”

The church was destroyed and a “lifetime of memories is just gone,” Brandt Malone, who has been going to the church for several years, told CNN.

“The hardest thing for our community right now is feeling like that security blanket has been ripped away,” Malone said.

Sanford rammed his pickup truck into the church before shooting congregants with an assault rifle. The building was set on fire, with flames reaching up to 70 feet.

Sanford was a sergeant during Operation Iraqi Freedom, starting in the summer of 2007. He received several medals for his service, a Marine Corps spokesperson told CNN.

He was married and had at least one child. A GoldFundMe page in 2015 said the family needed donations to help pay for a son, who was born with a rare genetic disorder.

Kris Johns, a Burton city council candidate, told the Detroit Free Press and the Detroit News that he spoke with Sanford on the campaign trail a few days before the shooting.

Johns recalled Sanford had a tirade against the church and described Mormons, which is the informal name given for members as the Church of Jesus Christ, as “the antichrist.”

“It was very much standard anti-LDS talking points that you would find on YouTube, TikTok, Facebook,” Johns told the Detroit News.

The council candidate recalled to the Free Press “there was no mention of anything right or left, blue or red. He said he saw Trump 2024 sign on the suspect’s fence.

NBC News confirmed an image loaded to Facebook in 2019 showed him wearing a “TRUMP 2020” shirt.

Johns said the man noted struggles with drug addiction.

A survivor at the shooting said there was no security at the church.

“We heard a big bang and the doors flew open,” Paula, who didn’t give her last name, told WXYZ TV. “And then everybody rushed out. We went through the church and through the parking lot … when we got in the cars and flipped around, that’s when the shooter started shooting at the car.”
