美国联邦调查局（FBI）表示，周日凌晨发生在德克萨斯州奥斯汀市中心的枪击案造成三人死亡、十四人受伤，这起枪击案“可能属于恐怖主义行为”。

据多位联邦执法部门消息人士向福克斯新闻透露，嫌疑人已被确认为恩迪亚加·迪亚涅，现年53岁，是一名入籍美国公民，出生于塞内加尔，居住在德克萨斯州普弗卢格维尔。

消息人士称，枪手身穿一件印有“真主”字样的运动衫，内搭一件印有伊朗国旗的内衣。福克斯新闻获得了一张据称是这名枪手的照片，照片显示他手持步枪，身穿一件印有“真主的财产”字样的毛衣。多位联邦消息人士告诉福克斯新闻，嫌疑人于2013年奥巴马执政期间入籍美国。

白宫新闻秘书卡罗琳·莱维特表示，唐纳德·特朗普总统已听取了有关奥斯汀枪击案的简报。

凌晨2点前，在西六街的布福德后院啤酒花园外，也就是人潮涌动的娱乐区，发生了一起枪击事件。警方称，嫌疑人驾驶一辆大型SUV在街区附近绕行数圈后开枪射击。

联邦调查局圣安东尼奥分局代理主管特工亚历克斯·多恩在周日的新闻发布会上表示，“显然，现在断定其确切作案动机还为时尚早，但嫌疑人及其车辆中的一些迹象表明，此案可能与恐怖主义有关。”

多恩补充道，“再次强调，现在下结论还为时过早。因此，我们正在与奥斯汀警察局的合作伙伴密切合作，对此案进行深入调查。”

消息人士称，目前至少有一份涉及联邦调查局特工的搜查令正在普弗卢格维尔执行。

拥有二十多年联邦调查局高级主管特工经验的杰森·帕克表示，调查人员认为迪亚涅可能是单独行动，而非隶属于某个有组织的团伙，并补充说，他们也在调查迪亚涅的精神状况。

“我的消息来源表明，他并非某个有组织犯罪团伙的成员，”帕克说，“这看起来像是一个独狼式作案，他可能是受到某种启发而非有人指使。”

帕克补充说，搜查令很可能涵盖迪亚涅的数字痕迹，包括他的设备、社交媒体账户和通信记录。

“调查人员将通过这些途径寻找他的激进化路径或与极端主义网络的任何联系，”他说，“他们将采访迪亚涅的同伴、家人、邻居和同事，以建立行为基线并识别任何被忽略的预警信号。美国烟酒枪炮及爆炸物管理局将追踪迪亚涅的手枪和步枪，以确定他如何以及何时获得这些枪支。”

当记者追问此案是否涉及国内或国际恐怖主义时，多恩表示，联合反恐特遣部队已经介入调查。

他补充道，“目前我们只能说，这很可能是一起恐怖主义行为。”

周日，德克萨斯州共和党参议员约翰·科宁在接受福克斯新闻数字频道采访时被问及这起枪击事件，他表示：“这起事件让我更加意识到，在人们越境之前对其进行审查的重要性。”

“部分问题在于，拜登政府四年来一直奉行开放的边境政策，让形形色色的人涌入美国，”科宁指责道。“这并非关乎人们继续入境的问题，因为我们知道特朗普总统已经加强了边境安全。这是关于已经在这里的人们将会发生什么事。”

警察局长丽莎·戴维斯表示，枪手“打开了双闪灯，摇下车窗，开始用手枪从车窗向外射击，击中了酒吧露台和酒吧门前的顾客。”

戴维斯说，嫌疑人随后驾车沿第六街向西行驶至伍德街，停车后，持步枪下车，继续向行人射击。

她补充道，“他根本没进酒吧。”

戴维斯说，周末人潮涌动时，附近警力部署的警员在大约“55-56秒”内做出了反应。警方在十字路口开枪击毙了嫌疑人。

据当地电视台KVUE报道，此次枪击事件发生之际，奥斯汀第六街娱乐区的安全问题持续令人担忧。近年来，该区域发生多起暴力事件，警方和商家正在努力改进人群控制措施。

“那家酒吧门前每个周末都乱成一团，好吗？这已经不是什么新鲜事了，”Blindside Tattoos纹身店和Blindside Lounge酒吧的老板雨果·门德斯告诉媒体。“这不一定是第六街的问题，而是某些酒吧……没有达到安全标准。”

当局已设立受害者服务热线，为寻求信息的家庭提供帮助。

The FBIsaid a shooting that left three people dead and 14 others wounded in a downtown Austin, Texas, rampage early Sunday was “potentially an act of terrorism.”

The suspect,identified as Ndiaga Diagne, was a 53-year-old naturalized U.S. citizen who was born in Senegal and lived in Pflugerville, Texas, multiple federal law enforcement sources told Fox News.

According to those sources, the shooter was wearing a sweatshirt that said “Allah” and an undershirt featuring an Iranian flag. Fox News has obtained a photo of the alleged mass shooter, armed with a rifle and in a sweater that says “property of Allah.” Multiple federal sources tell Fox News that the suspect was naturalized in 2013 during the Obama administration.

White House press secretary Karoline Leavitt said that President Donald Trump has been briefed on the Austin shooting.

The gunfire erupted just before 2 a.m. outside Buford’s Backyard Beer Garden on West Sixth Street, a packed entertainment district, after the suspect in a large SUV drove around the block several times before opening fire, police said.

“Obviously, it’s still way too early in the process to determine an exact motivation, but there were indicators on the subject and in his vehicle that indicate potential nexus to terrorism,” Alex Dorn, acting special agent in charge of the FBI’s San Antonio Field Office, said at a Sunday press conference.

“Again, it’s still too early to make a determination on that. That’s why we are investigating it very closely with our partners with Austin police department,” Dorn added.

Sources say at least one search warrant involving Federal Bureau of Investigation agents is currently being executed in Pflugerville.

Jason Pack, a retired FBI supervisory special agent with more than two decades of service, said investigators believe Diagne may have acted alone rather than as part of a coordinated group, adding that mental illness is also being examined.

“My sourcing suggests he was not part of an organized cell,” he said. “This looks like a lone actor who may have been inspired rather than directed.”

The search warrant will likely cover Diagne’s digital footprint, including his devices, social media accounts and communications, Pack added.

“That is where investigators will look for a radicalization pathway or any contact with extremist networks,” he said. “Associates, family, neighbors, and coworkers will be interviewed to build a behavioral baseline and identify any missed warning signs. ATF will trace the pistol and rifle to establish how and when he acquired them.”

When pressed by a reporter on whether the case involved domestic or international terrorism, Dorn said the Joint Terrorism Task Force is engaged.

“We’re just at this point prepared to say that it was potentially an act of terrorism,” he added.

Asked about the shooting, Republican Sen. John Cornyn of Texas on Sunday said in a Fox News Digital interview, “What it does emphasize to me is the importance of vetting people before they come across the border.”

“Part of the problem is that the Biden administration, for four years, had open border policies and let who knows what into the country,” Cornyn charged. “This isn’t about people continuing to come into the country, because we know President Trump has secured the border. This is about what happens with people already here.”

Police Chief Lisa Davis said the gunman “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.”

The suspect then drove westbound on Sixth Street to Wood Street, parked, exited the vehicle with a rifle and continued shooting at pedestrians, Davis said.

“He never entered the bar,” she added.

Officers staged nearby for weekend crowds responded within about “55-56 seconds,” Davis said. Police shot and killed the suspect at an intersection.

The shooting comes amid ongoing safety concerns along Austin’s Sixth Street entertainment strip, which has seen multiple violent incidents in recent years as police and business owners work to improve crowd-control measures, according to local KVUE.

“There is chaos in front of that bar every weekend, OK? This is not a new thing,” Hugo Mendez, owner of Blindside Tattoos and Blindside Lounge, told the outlet. “It’s not necessarily Sixth Street. It’s certain bars… that don’t carry the standard.”

Authorities have set up a Victim Services Unit hotline for families seeking information.
