In a separate news conference Thurday night in Massachusetts, federal prosecutors provided more details on the timeline of the suspect’s movements prior to the Brown University shooting and the killing of an MIT professor.
According to Leah Foley, U.S. attorney for the District of Massachusetts, the suspect, Claudio Manuel Neves Valente, rented a hotel room in Boston from Nov. 26 to Nov. 30.
On Dec. 1, he rented a gray Nissan Sentra with Florida plates from a car rental agency in Boston, and that same day, he drove “to the vicinity” of Brown University, Foley said.

His car was “observed intermittently” between Dec. 1 and Dec. 12 in the area of Brown University, Foley said. The mass shooting took place on Dec. 13.
Between Dec. 13 and Dec. 14, the suspect returned to Massachusetts, and on Dec. 15, “he murdered MIT professor Nuno Loureiro at Loureiro’s home in Brookline,” Foley said.

He then switched the plates on his rental car to an unregistered Maine plate, Foley said, and drove to the storage facility in Salem, New Hampshire, where he had rented a unit and where he was found dead Thursday.
“Investigators identified the vehicle that he had rented in Boston and drove to Rhode Island,” Foley said. The vehicle was seen outside of Brown, and there was security footage of a person who resembled him.
“There were financial investigations that were going on in the background that linked him, not only to that car, but to the hotels that he had rented,” Foley said.
Security footage also showed the suspect within a half-mile of Loureiro’s apartment, as well as footage showing him entering an apartment building “in the location of the professor’s apartment,” Foley said.
About an hour later, he was seen entering the storage unit in Salem, New Hampshire, where he was found dead Thursday, dressed in the same clothes that he was seen wearing right after Loureiro’s murder, Foley said.
