SALEM, N.H. — The individual suspected in the Brown University shooting and the killing of Massachusetts Institute of Technology professor Nuno F. G. Loureiro was found deceased inside a storage facility in Salem, New Hampshire, according to sources familiar with the investigation.

Authorities believe the individual died from a self-inflicted gunshot wound.

Suspect was not a US citizen but instead a legal permanent resident.

Law enforcement sources said the suspect had a storage unit registered in his name at the same facility where an abandoned vehicle connected to the investigation was previously located.

Investigators had not entered the unit prior to the discovery. Surveillance video reportedly shows the suspect entering the storage complex; however, it remains unclear whether he exited before his death.

The investigation involved extensive coordination among federal, state, and local law enforcement agencies, particularly in the area near the Salem, New Hampshire–Methuen, Massachusetts border.

Earlier, Methuen police issued a public advisory requesting that residents report any individuals on foot who appeared out of place or were behaving suspiciously. Authorities emphasized at the time that there was no known threat to the public.

Investigators determined that the suspect used a vehicle linked to both the Brown University shooting and the MIT professor’s killing.

According to officials briefed on the case, the vehicle was the same make and model in both investigations but displayed different license plates.

A witness-provided license plate number in the Brown University case led authorities to trace the vehicle’s history, which ultimately connected it to the Brookline homicide.

Law enforcement later located the vehicle in Salem after a license plate reader flagged one of the associated plates, prompting a significant police presence in the area.

Officials said the suspect appeared to have employed multiple countermeasures to avoid detection, including switching license plates across jurisdictions and taking steps to limit identification through surveillance cameras and facial recognition technology.

Authorities noted that these actions suggested advance planning and drew comparisons to other high-profile manhunts in which suspects attempted to conceal their identities while evading capture.

The investigation remains ongoing, and officials have not yet released the suspect’s identity or additional details pending formal confirmation and notification procedures.
