“Yeah, look, I think it’s fair to say that, ah, there is no basis to consider him a person of interest. So that’s why he’s being released,” Rhode Island Attorney General Peter Neronha said.

In a post on X, the Providence Police wrote, “Tonight, we announced that the person of interest is being released. The investigation has been ongoing and remains fully active between all agencies. Since the first call to 911, we have not received any specific threats to our community.”

Monday at 2:30 p.m.: Police release additional surveillance footage of a person of interest:

5:15 p.m.: The FBI and Providence Police released new images and video of a person of interest, showing someone wearing dark clothing, captured from surveillance cameras.

The images were retrieved around 2 p.m. Saturday, two hours before the shooting, authorities said at a news conference on Monday. The person of interest was described as a male, approximately 5 feet 8 inches tall with a stocky build.

Authorities added during the news conference that the shooter used a 9mm handgun.

Police said Neves-Valente used his real name on a rental car agreement, which helped officials locate the suspect. Neves-Valente rented a Nissan Sentra with Florida plates from Alamo Rent A Car in Boston, Massachusetts, on Dec. 1.

10:48 p.m.: U.S. Attorney Leah Foley said Neves-Valente was also responsible for the murder of Massachusetts Institute of Technology professor Nuno F. Gomes Loureiro, who died after suffering “apparent gunshot wounds” on Monday evening.

Retired FBI Supervisory Agent Jason Pack told Fox News Digital “people want answers,” noting there’s an intense amount of pressure on law enforcement.

“Parents want to know their kids are safe. Students want to know if they can move freely on campus. Families of the victims want justice, and they deserve it,” Pack said. “There is also pressure. Investigators feel it. Prosecutors feel it. University officials feel it. Families of the victims carry it every hour of every day. Pressure, however, does not solve cases. Evidence does.”

City officials said Wednesday they had suspended the entertainment license for Icon, a Boston nightclub, after a woman suffered a medical emergency there over the weekend and later died.

The city’s licensing board is expected to hold a hearing on the future of Icon’s liquor license “in the coming weeks,” according to a statement from the mayor’s office.

Police arrived at the Warrenton Street venue, in the Theater District, just before 12:30 a.m. on Sunday and found a person lying on the dance floor, unresponsive and without a pulse, according to an incident report. Family members on social media identified the woman as Anastaiya Colon and said she had been celebrating her sister’s birthday when she collapsed.

Emergency medical personnel performed chest compressions and took Colon to Tufts Medical Center, according to the report. Family members said Tuesday that she had died.

“Any loss of life in our community is a horrible tragedy and our condolences go out to the family and loved ones,” Mayor Michelle Wu said in a statement Wednesday.

Family members have accused the nightclub of negligence, alleging that, once alerted to the medical emergency, Icon staff failed immediately to call 911, only stopped the dance music for a few minutes, and did not clear the way for emergency personnel once they arrived.

“Their negligence and incompetence to control and clear a crowd for professionals ensured it was too late to save her,” Bonnell Stackhouse, Colon’s former partner, alleged in a social media post.

Boston police detectives are investigating the incident, according to Officer Mark Marron, a department spokesperson. A spokesperson for the Suffolk district attorney’s office said Wednesday morning that there are “no indications of criminality.”

In a statement to the Globe on Wednesday, the club said its staff had acted appropriately.

Club management said it conducted interviews with employees and reviewed security footage that showed CPR was administered “within a minute” of staff being notified of the medical emergency.

EMS was contacted within two minutes, and Boston police arrived within six minutes, the club said.

“We hope the family finds some comfort knowing that Boston Police, Boston EMS, and the Club Staff worked diligently and efficiently in responding to this unfortunate situation,” club management said.

According to the police report, however, the first officers to arrive on the scene were on a routine patrol outside the nightclub when they were flagged down by one of Colon’s friends.

Police also said in the report that the large crowd inside the club did not comply with orders to give space to emergency medical personnel, forcing them to shut down the club and order the patrons to leave.

Icon had planned to hold a New Year’s Eve event, headlined by DJs JayRoc and Roniflee, according to its social media accounts. It was unclear Wednesday whether that event would take place.

Colon, known as “Nena,” leaves behind two children, one aged 9 and the other 6 months old, according to a fund-raiser in her name.
