Brown University and MIT gunman Claudio Neves Valente had been dead for two days before he was found by law enforcement, his autopsy reveals.
The body of Neves Valente, 48, a former Brown student and Portuguese national, was discovered Thursday evening after a six-day manhunt.
Investigators believe he is responsible for fatally shooting two students and wounding nine others at Brown, and then two days later killing Massachusetts Institute of Technology (MIT) professor Nuno F G Loureiro.
New Hampshire Attorney General John M Formella announced Friday that the state's chief medical examiner confirmed he died of a self-inflicted gunshot wound, ruled as suicide.
Additionally, the report estimated he died on Tuesday, around two days before he was discovered at a storage facility in Salem, New Hampshire.
Neves Valente revisited his former university in Providence, Rhode Island, on December 13 and fired at least 44 rounds from his 9mm pistol, killing two students and injuring another nine.
'There are some witnesses who said he said nothing. There are some that say he made a barking noise,' AG Neronha said, adding: 'Don't ask me. I don't know why. And that's it. There is no other spoken word beyond that, that we are aware of.'
The two Brown students killed during the study session were 19-year-old sophomore Ella Cook and 18-year-old freshman Mukhammad Aziz Umurzokov.
