A man who shot dead two people and wounded 14 others at a crowded bar in Austin, Texas, has been identified as Ndiaga Diagne, a 53-year-old naturalised US citizen originally from Senegal, law enforcement sources told CBS News. The attack took place at about 02:00 local time at Buford’s Backyard Beer Garden near the University of Texas at Austin campus, as hundreds of people were leaving the venue at closing time. According to authorities, Diagne drove a large SUV around the block several times before stopping in front of the bar and opening fire from the driver’s window with a pistol, striking patrons on the front patio.
