Suspect in Brown and M.I.T. killings had years of isolation and resentment

Authorities identified Claudio Neves Valente as the suspect in shootings that killed two Brown University students and an M.I.T. professor and wounded nine others. He killed himself not long after the attacks, and the Justice Department released transcripts of four recordings found with his body in a storage facility in Salem, N.H.

Former classmates, co‑workers and relatives told The New York Times that Mr. Neves Valente had once been a top student in Portugal’s Instituto Superior Técnico, briefly attended Brown as a doctoral student in 2000 and later worked for seven years at the Portuguese internet company SAPO.

They described a long period of withdrawal after he returned from Brown: he stopped seeing family, quit his job abruptly in the fall of 2013 after a cousin’s funeral, sold his Lisbon apartment and ceased contact with friends. His mother told acquaintances he had mental health issues but refused treatment, the reporting said.

The transcripts, translated from Portuguese and released by federal officials, record rambling diatribes in which he refuses to apologize and casts the attacks as acts of defiance and revenge, saying the world “cannot be redeemed” and that he “wouldn’t be the one who ended up suffering the most from all of this,” according to the Justice Department.
