A shooting early Sunday in a crowded entertainment district in the southern city of Austin, Texas has left one person dead and three others injured.
Austin Police Chief of Staff Brian Manley said an unidentified gunman began shooting into the crowd after an initial disturbance, creating a chaotic scene.
A search is underway for the suspect and the motive for the attack was not immediately clear.
Police are asking the public for information, including videos, in an attempt to find the shooter, who is believed to be in his 20's.
Moments after the shooting, Manley said a man opened fire several blocks away during a confrontation in a parking garage. Bystanders tackled the gunman, who was hospitalized for injuries sustained when he was apprehended. No one was believed to have been shot in that incident.
Police originally thought the two shootings were related and involved an active shooter. But Manley said the initial investigation found they were two unrelated incidents.
The recent targeting and killing of police officers during a peaceful march in Dallas, protesting police brutality, has police forces across the country, especially Texas, on high alert.
