Austin Shooter Went On Crazed Rant Ahead Of Attack
Investigators are examining the online activity of the suspect accused in Sunday’s mass shooting in Austin after authorities said the attack may have a “potential nexus to terrorism.” The suspect, identified as 53-year-old Ndiaga Diagne, allegedly opened fire shortly before 2 a.m. outside a crowded downtown bar, killing three people and injuring 13 others.
Law enforcement officials say Diagne, a naturalized U.S. citizen originally from Senegal, was taken into custody following the shooting. As the investigation unfolds, attention has increasingly focused on a social media account believed to belong to him, which reportedly contained a stream of inflammatory and hostile comments directed at various religious and political groups.
The account, operating under the handle @NdiagaDiag88249 on X, was created in October 2024 and quickly began posting controversial messages. According to reports, many of the posts included antisemitic, anti-Christian, and misogynistic language, several of which were flagged by the platform as “potentially sensitive content.”
Among the posts cited by investigators was a message from August 2025 that praised what the author described as the “Islamic revolution” while directing hostile remarks toward critics of Iran and Islam. That comment was reportedly posted as a reply to Iranian Foreign Minister Seyed Abbas Araghchi during an online exchange about U.S. and Israeli policy in the Middle East.
Other posts targeted American political figures. In several messages, the account criticized President Donald Trump and Israeli Prime Minister Benjamin Netanyahu in harsh terms. Some posts were directed at right-leaning influencers and Trump supporters, using vulgar insults and antisemitic slurs.
Beyond political commentary, the account also contained posts attacking women with explicitly misogynistic language, including remarks suggesting women should remain confined to traditional domestic roles.
Authorities are reviewing the posts as part of a broader effort to determine the motive behind the shooting. Investigators say the suspect’s clothing and items recovered from his vehicle may also provide clues about his ideology.
According to officials, Diagne was wearing a sweatshirt that read “Property of Allah” and an undershirt featuring the Iranian flag at the time of his arrest. Police also reported recovering a Quran from his vehicle during the investigation.
While authorities have not yet formally labeled the attack as terrorism, they confirmed the possibility is under active review. One line of inquiry involves the timing of the shooting relative to recent geopolitical events. The attack occurred just one day after reports that Iran’s Supreme Leader, Ayatollah Ali Khamenei, had been killed during the escalating conflict involving the United States and Israel.
Investigators are examining whether those developments may have influenced the suspect’s actions or rhetoric online.
For now, officials emphasize that the investigation remains ongoing. Detectives are analyzing digital evidence, reviewing the suspect’s social media activity, and interviewing witnesses as they attempt to piece together the motivations behind one of Austin’s most serious acts of violence in recent years.
