Claudio Neves Valente, the man responsible for the Brown University mass shooting and the killing of a nuclear scientists at MIT, had been dead for two days before his body was discovered in a storage unit.
An autopsy revealed the 48-year-old Portuguese national died of a self-inflicted gunshot wound to the head on Tuesday, two days before police found his body.
Inside the storage unit, police also found a satchel with two guns.
Valente, a PhD student at Brown more than 20 years ago, was identified as the culprit of the mass shooting there last weekend that killed two and injured nine more.
Students Ella Cook, a 19-year-old sophomore from Alabama, and Mukhammad Aziz Umurzokov, an 18-year-old Uzbek American freshman, were killed in the shooting last Saturday.
Valente then travelled 50 miles and shot dead MIT professor Nuno Loureiro at his Brookline townhouse, two days later.
Valente and Loureiro had been classmates at the Instituto Superior Técnico in Portugal.
The killer’s motives are, at present, unclear, authorities say.
“I don’t think we have any idea why now, or why Brown, or why these students, why this classroom,” Rhode Island Attorney General Peter Neronha told reporters at a Thursday press conference.
It’s claimed Valente made strange “barking” noises as he fired during his rampage at Brown.
