Suspect killed himself after allegedly killing an MIT professor and two Brown University students

An autopsy report on the suspect in the mass shooting at Brown University and the killing of an MIT professor in Massachusetts has shown that he died from by suicide two days before he was found in a storage locker on Thursday.

The New Hampshire attorney general’s report estimates that Claudio Manuel Neves Valente, 48, a Portuguese national who had been living in the US, died on 16 December, the same day that his fellow countryman, MIT nuclear physics professor Nuno Loureiro died at a hospital in Massachusetts.

Three days earlier, authorities have said, Neves Valente was responsible for a shooting in Rhode Island that claimed the lives of two students, Ella Cook and Mukhammad Aziz Umurzokov, and injured nine others in Brown university’s Barus & Holley engineering building.

The two crimes were not immediately linked, but investigators putting together a timeline of Neves Valente’s movements across three states have said it was a Reddit post by a homeless former Brown student name “John” that helped them to identify Neves Valente as a person of interest.
