Providence Mayor Brett Smiley addressed the press at noon alongside the police and fire departments following Saturday’s deadly shooting at Brown University that left two dead and nine injured.

The mayor announced earlier Sunday morning that a person of interest had been arrested and the shelter in place had been lifted.

The shooting paralyzed the campus, with students sheltering in place for hours. Nine students with gunshot wounds were taken to the hospital, with one in critical condition. An FBI agent says the arrest took place at a hotel in Coventry, about 20 miles (32 kilometers) from Providence.

Police Chief Col. Oscar Perez did not give any details about the progress of the investigation except to say it was progressing “extremely fast.”

Meanwhile, the city’s mayor said he visited victims in the hospital.

“The resilience that these survivors showed and shared with me was frankly overwhelming,” Smiley said.

As of Sunday morning, one student had been released from the hospital, said Paxson. Seven others were in critical but stable condition and one was in critical condition.

Armed with a handgun, the shooter fired more than 40 9 mm rounds, according to a law enforcement official.

Authorities as of Sunday morning hadn’t recovered a gun but did recover two loaded 30-round magazines, said the official, who spoke on the condition of anonymity because they were not authorized to publicly discuss the investigation.

Perez said the person in custody was in their 30s and that investigators were not searching for anyone else but that no one has been charged yet. He declined to say whether the detained person had any connection to Brown. The person was taken into custody at a Hampton Inn hotel in Coventry, Rhode Island, about 20 miles (32 kilometers) from Providence, where police officers and FBI agents remained Sunday, blocking off a hallway with crime scene tape as they searched the area.
