Police respond to an active shooter in the engineering building on the Brown University campus.

A person of interest is in custody after a shooter opened fire at Brown University over the weekend, killing at least two people and wounding nine others, officials announced.

NBC News and the Washington Post, citing officials briefed on the investigation, reported the person of interest as Benjamin Erickson. USA TODAY has not independently verified that report. Erickson, 24, has not been charged and has not been named as a suspect in the shooting.

The attack took place one day earlier at the Providence, Rhode Island, school at about 4 p.m., law enforcement said, prompting a shelter-in-place order that forced students and faculty to spend the night on campus.

Providence Mayor Brett Smiley later told reporters that of the nine people shot, one had been discharged, one remained in critical condition, and the other seven victims were in stable condition.

Officials have not yet released the names of those who were killed. Smiley also said that not all of the victims' families have been notified as of Dec. 14.

Law enforcement was still reviewing surveillance footage, coordinating with prosecutors, collecting evidence, and speaking to witnesses on Sunday to gather more information about the suspected shooter, Perez explained.

Who is person of interest in the Brown University shooting?

Police have released a few details about the person of interest.

"It takes time, we have to make sure we have all the right evidence to prosecute," Perez said during an afternoon news conference.

Rhode Island Gov. Daniel James McKee asked the nation to pray for the victims, their families, and all those involved.

"The community is suffering and in pain," McKee said during the news conference. "We stand with you."

Where was the person taken into custody?

The person detained was taken into custody early in the morning at a hotel in Coventry, Rhode Island, according to an FBI update. Coventry is located in Kent County, about 16 miles southwest of Brown.

FBI Director Kash Patel said law enforcement used cellular data to track the person of interest to a hotel room where he was detained by U.S. Marshals and Providence police, based on a tip from the Coverntry Police Department.

The person, local WJAR-TV reported, was apprehended at the Hampton Inn there.

"We have deployed local and national resources to process and reconstruct the shooting scene - providing HQ and Lab elements on scene," Patel wrote in an update on social media. "We set up a digital media intake portal to ingest images and video from the public related to this incident."

Patel said the FBI, aided by local police, continued to investigate the case."The FBI’s victim specialists are fully integrating with our partners to provide resources to victims and survivors of this horrific violence," Patel wrote.

Is there only one shooter?

Perez told reporters that officers are not searching for anyone else connected to the shooting and did not name the person of interest. He did not say whether they are a student or a faculty member at the school.

The mayor also told reporters that the case was continuing to develop and remains under investigation.

How long can someone be held by police in Rhode Island?

Rhode Island District Court rules dictate that a police officer making an arrest via a warrant must present the alleged suspect “without unnecessary delay before a judge.”

If investigators make an arrest without a warrant, the rules again require the police to present the alleged suspect “without unnecessary delay” before a District Court judge. The rules require, too, that a bail hearing before a judge or justice of the peace be held promptly.

An alleged suspect has the right to ask to leave police custody, if he or she isn’t charged, and request a lawyer.

Do you have information about the Brown University shooting?

Police were asking members of the public with security cameras near the Barus and Holley building or on Hope Street in Providence to review their camera footage to see if they captured anything around the time of the shooting.

Anyone with information about the shooting or the suspect is asked to call 911 or contact the Providence police non-emergency line at 401-272-3121.
