A man who recently attempted to enter a Dallas church with a tactical rifle was charged with a federal firearm crime stemming from a 2022 shooting, the U.S. Attorney’s Office for the North District of Texas announced.

Russell Alan Ragsdale, 25, was arrested Friday and made his initial appearance Monday on a possession of a firearm by an unlawful user of a controlled substance charge.

On Nov. 2, a church reported to Dallas police that Ragsdale was at the location with a gun, according to federal court documents. The church was not named in the filing.

Based on surveillance footage and witness interviews, officers determined Ragsdale arrived at the church about 5 p.m. while Mass was being celebrated with about 100 church members, according to an affidavit. He entered about 5:05 p.m.

“At 5:07 p.m., [Ragsdale] stood from his front row seat and approached the priest, embraced him and kissed him on both cheeks,” the affidavit says. Ragsdale “handed the priest a note that said, ‘May peace be with you.’”

Ragsdale remained in the church for about five more minutes before returning to his car. He put on a black and white poncho, retrieved a rifle from the trunk of the car, and then closed the three gates to the church parking lot, according to the affidavit. Ragsdale tried to reenter the church with the gun about 5:35 p.m., but parishioners had locked the doors.

A parishioner talked to Ragsdale outside after he placed the rifle on the ground. Officers arrived a few minutes later and arrested him.

The arresting officer noted “an odor of alcohol” coming from Ragsdale, the affidavit says.

During this investigation, police learned Ragsdale had been arrested two years ago as a suspect in a Seagoville slaying. He had faced a felony murder charge in the February 2022 killing of his roommate, but the case was later dismissed.

At the time, Ragsdale told police his roommate attacked him so he “shot him many times” in self-defense, according to court documents.

“Officers recovered three firearms, including a 10mm Glock and an AR-15 rifle, and almost two grams of hallucinogenic mushrooms from the residence,” the news release said. ” An analysis of Mr. Ragsdale’s phone showed a history of drug use dating back to November 2021, as well as evidence of purchasing and using hallucinogenic mushrooms on Feb. 2, 2022.”

Pursuant to a search warrant issued, earlier this month Dallas police received copies of information, including messages, from Ragsdale’s phone that indicated he used illegal drugs leading up to the February homicide, according to court documents.

If convicted, Ragsdale faces up to 15 years in prison.
