SALEM – The suspect in the Brown University mass shooting that killed two students and wounded nine Saturday and the murder of an MIT professor Monday has been found dead in a Salem, N.H. storage unit, according to law enforcement officials.

Providence, R.I. police on Thursday announced the death of Claudio Manuel Neves Valente, the 48-year-old former Brown University graduate student responsible for the murders of the two Brown University students.

A Rhode Island state court, based on an affidavit from a Providence Police Detective, issued a state arrest warrant for Neves Valente charging him with two counts of murder of the students and 23 felony counts of assault and felony firearms offenses. The affidavit can be read here.

Law enforcement tracked Neves Valente to a Salem, New Hampshire, storage unit, where they found him dead from a self-inflicted gunshot Thursday evening, police said.

Neves Valente was born in Torres Novas, Santarem, Portugal and was a Legal Permanent Resident of the United States. Neves Valente arrived in the United States in August 2000 as an F-1 student at Brown University and subsequently obtained U.S. lawful permanent residency in April 2017. While at Brown University, he was enrolled in a doctoral program but subsequently withdrew from the university, officials said.

CBC reported that law enforcement officials said Neves Valente also killed MIT professor Nuno Loureiro on Monday in Brookline, Mass.

“Nuno Loureiro taught plasma physics at the elite university and led its Plasma Science and Fusion Center. The 47-year-old was shot at his home in Brookline, Massachusetts, Monday and died at a nearby hospital the next day,” CBS reported.

The investigations continued into the night as federal, state and local police tried to piece together a timeline in search of connections linking the killer to the students in Rhode Island and Loureiro in Brookline, Mass.
