Austin mass shooting: Timeline traces suspect’s rap sheet as terror link probed

The gunman involved in the tragic shooting outside a bar in Austin, Texas, on Sunday morning had images of Iranian leaders in his apartment, sparking an investigation into a “potential nexus to terrorism,” according to reports.

Ndiaga Diagne, 53, who was originally from Senegal but had become a naturalized U.S. citizen, was identified as the suspect in the shooting that occurred just before 2 a.m. outside Buford’s Backyard Beer Garden. Law enforcement sources disclosed to Fox News that inside Diagne’s residence, investigators found pictures of Iranian leaders along with an Iranian flag. The incident resulted in the deaths of three people, including Diagne, and left 14 others injured, according to officials.

Additional information provided to Fox News revealed that Diagne was dressed in a sweatshirt reading “Property of Allah” and an undershirt featuring an Iranian flag during the attack. A Quran was also discovered in his vehicle.

At a press conference held on Monday, authorities confirmed that 21-year-old Savitha Shan and 19-year-old Ryder Harrington were among those who lost their lives in the shooting.

Police Chief Lisa Davis said Diagne “put his flashers on, rolled down his window and began using a pistol shooting out of his car windows, striking patrons of the bar that were on the patio and that were in front of the bar.”

Davis said that the suspect exited his vehicle and shot at individuals, but didn’t enter the bar.

FBI Acting Special Agent in Charge Alex Doran said during a press conference on Sunday that investigators are looking into a motive.

“Obviously it’s still way too early in the process to determine an exact motivation,” Doran said. “But there were indicators that on the subject and in his vehicle that indicate potential nexus to terrorism.”

Retired FBI Supervisory Agent James Gagliano, who was once on the agency’s counterterror unit, told Fox News Digital the shooting “seems to have all the earmarks of a terrorist attack.”

“Was this somebody who was an aspirant that saw somebody else do this and said, ‘I want to do the same thing?’ Or was this person directed?” Gagliano said. “It clearly looks like a lone wolf type of thing, so it looks like an inspired or an aspirant, in my estimation.”
