The suspect in the Dec. 13 mass shooting at Brown University has been found dead by suicide in a storage unit in Salem, New Hampshire, authorities said.

He was identified as 48-year-old Claudio Manuel Neves Valente, a former Brown student.

The campus shooting killed two students and wounded nine others during a study session in an engineering building amid final exams.

Valente is also believed to be responsible for the fatal shooting of MIT professor Nuno Loureiro in Brookline, Massachusetts, two days later, according to federal prosecutors, CBS News has reported.

Investigators had previously struggled to identify or locate the suspect due to limited security footage.
