Brown University suspect found dead after six-day manhunt

Loureiro, 47, a Portuguese nuclear and engineering professor at MIT, was shot "multiple times" on Monday inside his home and was taken to a nearby hospital, where he was pronounced dead on Tuesday.

The attack came days after a gunman burst into Brown University's engineering building and opened fire during final exams. Six victims remain in hospital.

The two fatalities have been named as students Ella Cook, 19, and Mukhammad Aziz Umurzokov, 18.

A multi-state manhunt lasting nearly a week followed the Brown shooting.

On Wednesday police released new footage of a person of interest walking around the campus.

The FBI offered a $50,000 (£37,000) reward for information leading to the identification, arrest and conviction of the shooter.

The suspect was discovered on Friday through a combination of evidence and tip offs from members of the public.

Rhode Island attorney general Peter Neronha said Valente was found dead with a satchel and two firearms.

Initial findings suggest Valente died of a self-inflicted gunshot wound. Police did not disclose how long he might have been inside the storage unit.

"Even though the suspect was found dead tonight our work is not done. There are many questions that need to be answered," FBI special agent in charge of Boston Ted Docks said.

The FBI has deployed some 500 agents to assist local authorities in the investigation, Docks added.
