Authorities in Austin, Texas say three young people are in custody after a weekend series of shootings that injured four people. Police and city officials describe at least 10 incidents and say the shootings appear random. In their accounts, the suspected attackers are alleged to have fired at people and also targeted buildings and houses while driving through parts of the city. Sources also say the spree began with a stolen car and continued across the Austin area. Austin officials temporarily ordered residents in a large southern section of the city to shelter in place during the incidents, citing the apparent unpredictability of the attacks. Police say four people were injured and that the suspects are detained as the investigation continues. Reporting from multiple outlets describes the arrests as involving three suspects, including two teenagers, who were taken into custody shortly after the shootings. The mayor and police chief are cited as describing the activity as indiscriminate, and officials provide ongoing updates as authorities work to determine the full scope of the shootings and the suspects’ involvement.
