A truck driver warned that he would commit a mass shooting at a church in Memphis on Thursday, authorities say in newly filed court records.

Thomas Matthew McVicker was apprehended in Indianapolis before the plan could be carried out, according to court papers filed Monday. It’s the most recent case in a string of men being arrested around the country for threatening to carry out shootings.

McVicker made “credible threats to conduct a mass shooting and suicide,” an FBI special agent said in a sworn affidavit.

The circumstances of his arrest in Indiana weren’t outlined in the affidavit.

Earlier this month, McVicker’s friend in southern Alabama told a Florida FBI agent that McVicker has been considering “shooting a church up” or killing people on the street.

Later, in a telephone call, the friend said McVicker told her the church shooting would happen when he was in Memphis on Thursday and that he “intended to take his knife and slit the pastor’s throat.”

According to WTTV in Indianapolis, court documents state that McVicker texted to a friend, “I’m thinking about shooting a church up but I’m afraid how it will affect my family in the flesh when I’m gone,” he wrote. “So I think I’m just gonna kill some people on the street and get away with it then kill myself.”

When his friend urged him to get some help, McVicker replied, “I’m telling you there won’t be a glorious turnaround for me, I’m going to be gone soon forever.”

His mother told the FBI he owned a Ruger P90 handgun and sometimes uses cocaine and methamphetamine. She also said her son is being treated for schizophrenia.

The FBI says it confirmed with McVicker’s employer that he requested leave time Thursday and that he indicated in the request that he would spend the leave time in Memphis, the affidavit states.

The affidavit doesn’t specify a motive, nor does it identify a specific Memphis church.

The Memphis Police Department was notified of the threat, which did not mention a specific church, police spokesman Louis Brownlee said Tuesday. Memphis police work regularly with state and federal authorities on these types of threats “to stay ahead of the curve,” Brownlee said.

Earle Fisher, pastor at Abyssinian Missionary Baptist Church in Memphis, said he would be reaching out to his congregation to tell them about the threat and inform them that the church has security measures in place.

“It’s tragic that we are in a climate that even in your house of worship, in what is supposed to be a sacred and safe space, you have to take up measures that might include making sure that you have armed security in your sanctuary to make sure that your parishioners are safe,” Fisher said.

Court records in Alabama show McVicker received a ticket for driving a truck in an improper lane in Jefferson County, which includes Birmingham, in June 2014. He was working for Swift Transportation of Gary, Indiana, at the time, records show. McVicker failed to pay the fine until 13 months later, after his driver’s license was suspended, records show.

Court records list McVicker’s address as Punta Gorda, Florida, but his Alabama friend told the FBI that McVicker lives in his semi. The records don’t list a lawyer who could be reached for comment on McVicker’s behalf.
