The attacker who killed three people and wounded more than a dozen at a bar in Austin, Texas, appears to have posted antisemitic, anti-Christian and misogynistic content in the roughly 18 months before the shooting, law enforcement sources said. The rampage occurred early Sunday, one day after the U.S. and Israel struck Iran.
Investigators believe an X account created in October 2024 and last active in December is linked to the gunman. Sources said the account contained pro‑Iranian messaging, pro‑Islam comments and anti‑Christian posts, though they found no messages explicitly indicating plans to attack.
One April post amid rising Israel‑Iran tensions read, “THE ISLAMIC REVOLUTION IS ETERNAL … you Zionist and islamophobes can be angry all you want but you can’t do a damn thing about it no matter what.” That reply referenced an April 28 post by Iran’s foreign minister criticizing former President Trump and Israeli Prime Minister Benjamin Netanyahu.
Police identified the shooter as 53‑year‑old Ndiaga Diagne, who was killed by officers in a shootout. At the scene he wore a T‑shirt bearing a design similar to the Iranian flag under a hoodie reading “Property of Allah.” Investigators said a Quran was found in the SUV he drove. A search of his Austin apartment turned up an Islamic Republic of Iran flag and photographs of Iranian regime leaders, a person with direct knowledge of the probe said.
Sources said Diagne had a history of mental health issues; Texas officers previously responded to a suicidal call involving him. U.S. officials said he was an immigrant from Senegal who arrived in 2000 and became a U.S. citizen in 2013. While living in New York, he was sued for severely injuring a woman in a vehicle crash; details and the lawsuit’s resolution remain unclear. Records show four arrests between 2001 and 2016; the 2001 arrest — the only unsealed record — was for illegally selling sunglasses.
Multiple social media accounts use a username matching the gunman’s name. The X account investigators highlighted included posts disparaging Christianity (calling it “fake” and using vulgar language about figures such as Mary), praising Muslims as worshiping “THE ONE AND ONLY TRUE GOD,” and criticizing political leaders. One post called Trump “A shameless clown”; another described Netanyahu as “Evil.” In December, the account replied to a meme with a misogynistic line: “SPERM and have built everything in this world.” Several replies targeted right‑wing influencer Laura Loomer, including an obscene slur accusing “you and your Israel first acolytes fake Jews” of hypocrisy.
