The suspect in the Brown University shooting has been found dead after a police search, according to US media.
On Thursday night, hordes of police officers and FBI agents were seen surrounding a storage facility in Salem, New Hampshire in a bid to track down the supposed gunman.
But then, a police source told Fox News that the alleged shooter had been found dead - with what appeared to be a self-inflicted gunshot wound.
Police said the dead suspect was a 48-year-old Portuguese man named Claudio Manuel Neves-Valente.
Neves-Valente studied physics at Brown from autumn 2000 to spring 2001, according to university boss Christina Paxson.
He went on a leave of absence and ultimately withdrew in 2003.

Authorities had earlier been probing a link between the Brown attack and a mysterious killing at another elite American university.
A Boston federal official went onto confirm Neves-Valente was the shooter in both cases.
An MIT professor - fellow Portuguese Nuno Loureiro, 47 - was shot dead two days after the deadly attack at Brown.
The FBI had previously said it was unaware of any connection between the incidents.

Brown University is located in Providence, Rhode Island. The MIT shooting occurred roughly 50 miles north in Brookline, a suburb of Boston.
Two students were killed and nine others wounded at Brown when Neves-Valente opened fire in a classroom inside the university's engineering building on Saturday before fleeing the scene.
Then, on Monday evening, Prof Loureiro was shot at his home in Brookline.
The 47-year-old physicist and nuclear fusion scientist succumbed to his injuries at hospital the following day.
Prof Loureiro was married and had led MIT's Plasma Science and Fusion Centre since last year.

Despite Brown having 1,200 cameras on campus, the shooting took place in an older section of the engineering building with minimal surveillance coverage.
Police believe the shooter used a door facing a residential street to enter and exit, avoiding detection.
Providence mayor Brett Smiley acknowledged it was "a scary time in the city" and that families were likely discussing whether to remain in town over the holidays.
"We are doing everything we can to reassure folks, to provide comfort, and that is the best answer I can give to that difficult question," Mr Smiley said when asked about public safety.

Prof Loureiro grew up in Viseu, Portugal, and studied in Lisbon before completing his doctorate in London.
He worked as a researcher at a nuclear fusion institute in the Portuguese capital prior to joining MIT in 2016.
Last year, he was appointed to lead the Plasma Science and Fusion Center, one of MIT's largest laboratories with more than 250 staff across seven buildings.
He held professorships in physics and nuclear science and engineering, focusing on clean energy technology research.
