FBI probe finds Austin bar shooter was 'lone actor' in deadly March attack that killed 3

AUSTIN, Texas — The gunman who killed three people and wounded more than a dozen others in a mass shooting at a downtown Austin, Texas, bar in March was a “lone actor" and there is no evidence he was supported or directed by a foreign terrorist group, FBI investigators said Thursday.

The agency released a two-page update of its investigation into the attack on Buford's Backyard Beer Garden in the early morning hours of March 1 that ended when gunman, Ndiaga Diagne, was killed by police.

The shooting happened after the United States and Israel launched an attack on Iran. Diagne was wearing clothes with an Iranian flag design and the words “Property of Allah."

Despite lacking direct evidence of a motive for the shooting, investigators said Diagne was likely triggered into violent behavior by the war against Iran, “culminating in a violent, impulsive attack" at the bar, the report said.

Investigators determined Diagne admired Iranian leader Ayatollah Ali Khamenei, who had been killed. His affinity for Iran and its former leader were likely factors in the attack Diagne perpetrated on his own, investigators said.

“The investigation to date indicates Diagne was a lone actor,” the report said. He had never been the subject of an FBI investigation prior to the shooting.

Diagne, 53, was born in Senegal. He first entered the U.S. in 2000 on a B-2 tourist visa and became a lawful permanent resident six years later after marrying a U.S. citizen, according to the Department of Homeland Security.

“There is no evidence at this time that he was associated with a Foreign Terrorist Organization or that he received any direction, funding, or operational support for his attack,” the report said.

The bar is located in the city's popular hub of bars and nightclubs. Police said the gunman drove past the bar before circling back and firing the first shots from his SUV at people on the sidewalk and inside. He then parked, got out with a rifle and began shooting at people walking along the street before officers rushed to the intersection and shot him.

Austin Police Chief Lisa Davis has said officers arrived within 56 seconds of the first 911 call and killed the shooter after he fired at police.

Killed in the attack were 21-year-old Savitha Shan, 19-year-old Ryder Harrington and 30-year-old Jorge Pederson.

The FBI said the investigation into the attack remains open.
