Two people were found dead in a medical office in Austin, Texas, late Tuesday after a hostage standoff that lasted more than five hours, according to the police and local news reports.
It was not immediately clear how many people had been held hostage or who had taken them captive.
The police were first notified on Tuesday afternoon that a man with a gun was inside the medical office in central Austin, the TV news station KSAT reported. SWAT team members were seen and heard on a nearby street negotiating with a gunman on Tuesday evening, according to reporters on the scene.
Moments after the police said they were sending in a robot, Jody Barr, a journalist with the TV channel KXAN, wrote on Twitter that he had heard “loud explosions” and what sounded like gunshots at the building.
“Silence since,” he added.
The Austin Police Department later said on Twitter that the “SWAT situation” had ended. They said two people had been pronounced dead at the site.
The police did not immediately respond late Tuesday to phone calls or an email seeking comment. They said on Twitter that their homicide unit would provide more information on Wednesday morning.
Several news outlets identified the medical office as a branch of the Childrens Medical Group. Its website appeared on Tuesday to have been disabled, and a call to the branch office Wednesday morning went unanswered.
