A shooting on West 6th Street in Austin early Sunday morning left three people dead and 14 hospitalized. Acting Special Agent in Charge Alex Dolan said the incident is being investigated by the FBI as a possible act of terrorism.

The suspect was among the dead. He was shot by an Austin police officer, Police Chief Lisa Davis said.

The shooting happened just before 2 a.m. at Buford’s bar at the intersection of West Sixth Street and Rio Grande Avenue.

The FBI said it was too early in the investigation to determine the exact motive for the shooting. “The subject and his vehicle had indicators of a potential connection to terrorism,” Dolan said.

Law enforcement officials said they are not releasing the names of the suspect or victim at this time because the investigation is ongoing.

At a 9:30 a.m. news conference, Davis said the suspect drove the SUV around the block several times before stopping, turning on his flashers and rolling down the windows. He then shot and killed bar patrons on the patio and in front of the bar without entering the bar, police said.

The suspect then drove west, parked his car on nearby Wood Street and got out of the car with a rifle, Davis said. The suspect then shot and killed people walking on 6th Street before being shot and killed by responding officers, the chief said.

Austin-Travis County EMS received a call about a shooting at 1:59 a.m., and within 57 seconds, paramedics and police officers were on scene and treating patients, ATCEMS Chief Robert Lucritz said.

Davis said the male suspect was armed when police arrived, and three officers “fired back,” killing the man.

Lucritz said there were a total of 17 patients at the scene. Three people, including the suspect, were pronounced dead at the scene. Of the 14 people taken to the hospital, three are in critical condition. Lucritz said all critically ill patients were removed from the scene of the shooting within 24 minutes, and all remaining patients were removed from the scene within 47 minutes.

Austin Mayor Kirk Watson called the shooting a “pivotal moment” for Austin. “There is no doubt that the quick response of our police officers, paramedics and their professionals made a difference and saved lives,” he said.

University of Texas at Austin President Jim Davis said in a statement that he is deeply saddened by the shooting. “Our prayers are with the victims and all those affected, including members of the Longhorn family, and our hearts go out to their families, friends, classmates, professors, and loved ones,” he said.

Ochichi residents searching for loved ones in the aftermath of the shooting should call APD’s Victim Services Division at 512-974-5037. the police said.

“My condolences go out to everyone affected by this. This is a tragic and tragic incident,” Davis said.
