US Army soldier arrested for threatening to ‘walk into a synagogue with my AK’ and ‘kill every single Jew ‘ inside: feds

A US Army soldier stationed at a Louisiana base allegedly threatened to walk into a synagogue with an assault rifle and “kill every single Jew” there in a vile Discord rant, according to authorities.

Jakob Marcoulier, a 22-year-old soldier stationed at Fort Polk, was arrested last week after he allegedly launched violent antisemitic threats on the app in February, according to the United States Attorney’s Office for the Western District of Louisiana.

The FBI’s National Threat Operations Center received a tip in February about the user “el.bostino” and uncovered recorded audio from the gaming and messaging platform that captured an individual, later determined to be Marcoulier, threatening to commit a mass shooting at a synagogue, prosecutors alleged. 

“After this deployment if the Jews still have reign over our government, I am going to walk into a synagogue with my AK, with a 75-round drum mag, and all of my extra mags, with my level four plates, and my haka helmet that’s three plus, and I am going to kill every single Jew I know inside of that synagogue. And that’s my goal in life,” Marcoulier allegedly said. 

“You guys will never do anything about but I will. I just have to finish this, I have to go back overseas and do what I have to do. And then you’ll see me in the news. I promise you,” the statement continued. 

The US army soldier added that he’d “still kill these motherf—kers in order to make sure the white youth is f–king secured.”

The alleged white supremacist soldier flashed a smirk in his mugshot after he was cuffed last Thursday on a charge of transmitting a threat in interstate commerce.

Marcoulier faces five years behind bars in federal prison for the alleged threats, officials added.

“Threats against synagogues and Jewish Americans are threats to the religious freedom promised to every single one of us, and this Office and our law enforcement partners are committed to protecting those freedoms,” US Attorney Zachary A. Keller said in a statement. 

“This case demonstrates the FBI’s vigilance and swift action in identifying and taking action against those who perpetrate these threats, and our Office looks forward to seeing justice done in this case,” Keller added. 

Marcoulier has been kicked off Discord for breaking the platform’s hateful conduct policy. 

“Our dedicated teams work hard to identify and remove any users and spaces where bad actors are organizing around hateful ideologies and to prevent the misuse of our platform,” a Discord spokesperson said. “We proactively report cases that pose an imminent risk and aim to cooperate with law enforcement investigations where appropriate and in compliance with the law.”
