Suspect in Brown University, MIT professor shootings died days before he was found
The man believed to be responsible for the mass shooting at Brown University and the killing of an MIT professor in Brookline days later died on Tuesday, two days before he was found in a Salem, New Hampshire, storage unit , authorities said.
Claudio Manuel Neves Valente, 48, died of a self-inflicted gunshot wound to the head, an autopsy confirmed on Friday, according to New Hampshire Attorney General John M. Formella.
The autopsy revealed that Neves Valente took his own life on Dec. 16, the day after he shot and killed Nuno Loureiro in Brookline. Investigators had not yet identified Neves Valente as the suspect in either killing when he committed suicide.
Authorities tracked Neves Valente to a storage facility in Salem, New Hampshire on Thursday, where they found him dead. It was not clear at the time when he died.
Neves Valente had a personal connection to his two targets. He briefly attended Brown and knew Loureiro from a school they both attended in Lisbon, Portugal, according to authorities.
Still, a motive for the killings was not clear on Friday.
The mass shooting at Brown left two students dead and nine injured and touched off a massive manhunt that eventually extended across three states. Authorities identified Neves Valente as the shooter through surveillance footage and a key tip from a Reddit user .
