Chronology of Claudio Neves Valente's Movements in Brown University and MIT Tragedies

Following Claudio Neves Valente's passing, investigators provided a comprehensive breakdown of events prior to, during, and after the tragic incidents at Brown University and MIT.

This narrative is constructed from a Providence Police affidavit, insights from U.S. Attorney Leah Foley, and CBS News commentary.

Valente arrived in the United States on an educational visa and registered at Brown University to study physics. He paused his studies in April 2001 and officially exited the institution by July 2003.

Upon acquiring a green card, Valente relocated permanently to the U.S. His last known dwelling was unspecified in the documentation.

At 11:44 a.m., Valente is caught on Boston surveillance cameras at an Alamo car rental service.

Valente remained in accommodation in Boston between the 26th and 30th of November, as per Foley's account.

A worker at Brown University identified a man, aligning with the suspect's description, in the Barus & Holley building. He wore a surgical mask and sported a noticeable limp.

Valente procured a gray Nissan Sentra with Florida tags around 11:36 a.m. and subsequently headed towards Brown University's neighborhood, according to the affidavit.

His rental vehicle popped up periodically in the Brown University locale from December 1st to 12th, according to Foley's briefing.

The suspect was captured on video wearing a mask near Brown University on multiple occasions throughout one morning.

During the afternoon, he encountered another individual called "John" by the authorities. After a brief chase sequence, the two were seen again in proximity.

The suspect was later tracked to various streets around the university at intervals, including a parking area beside Barus & Holley.

At around 4 p.m., the assailant entered Barus & Holley and unleashed gunfire in an auditorium, tragically resulting in fatalities and wounding several. Authorities discovered considerable evidence involving bullet casings.

Surveillance from a university bus captured him fleeing the site shortly after the shooting.

The suspect was last visually confirmed at a separate location within Providence shortly after the incident, before presumably traveling back to Massachusetts over the weekend.

An initial suspect was questioned at a Rhode Island hotel but was eventually cleared as evidence began to suggest alternative leads.

Police amassed video collections from neighborhood cameras to track movements, narrowing down a description, including height and gait.

Victims and witnesses were consulted to identify the suspect after viewing the footage, leading to emotional confirmations of his identity.

John, a key witness, shared a meticulous account of his run-ins with Valente, who avoided direct engagement by changing directions sporadically.

Further investigative work pinpointed Valente near a fatal shooting in Brookline, where a professor lost his life, featuring similar modus operandi and attire.

Valente later appeared in connection with a storage site visit, wearing the same clothing as post-murder footage indicated.

The connection between Valente and the MIT professor was hinted at by shared academic backgrounds, though motives remain unconfirmed.

Valente's efforts to conceal his identity through methods such as altering vehicle plates demonstrated a high level of premeditation and strategy.

Collaboration among state and federal authorities eventually pinpointed Valente, with his subsequent demise from self-inflicted harm ceasing further inquiries.
