A Providence tipster named John has become the linchpin in the investigation that closed the case of the Brown University shooting and the subsequent murder of an MIT professor.
On a Saturday in Providence, a gunman fired more than 40 rounds inside a Brown engineering building, killing two students. Two days later, the same suspect allegedly shot a Massachusetts Institute of Technology professor in his Brookline home. The case remained unsolved for weeks, leaving the community in uncertainty. John’s anonymous tip finally provided the missing pieces that led police to identify the shooter.
Investigation Timeline

Police learned of John’s tip on Dec. 16, three days after the shooting and a day after the tip line was created. Until that point, officials had not linked a vehicle to the suspect. The tip pointed to a grey Nissan rental, prompting officers to obtain footage of a Nissan Sentra sedan with Florida plates. Using the surveillance company Flock Safety’s network of more than 70 street cameras, police gathered additional footage that helped confirm the vehicle’s identity.
Key Witness
John, who remains anonymous in the police affidavit, was credited with providing the details that led investigators to identify the shooter as 48-year-old Claudio Neves Valente. John recalled meeting Valente in the engineering building’s bathroom hours before the attack, noting his clothing was ‘inappropriate and inadequate for the weather.’ Later, outside the building, Valente turned toward the Nissan when John saw him, sparking a brief cat-and-mouse chase. John shouted, ‘Your car is back there, why are you circling the block?’ The suspect replied, ‘I don’t know you from nobody,’ and then asked, ‘Why are you harassing me?’
Police Response
Rhode Island Attorney General Peter Neronha praised John’s contribution, saying, “He blew this case right open,” and added, “When you crack it, you crack it.” The tip forced police to investigate the vehicle connection and led to the identification of the suspect’s residence. After the tip, officers were able to locate Valente’s home and gather evidence linking him to both shootings. The investigation culminated in the discovery of the suspect’s body, found dead from a self-inflicted gunshot wound.
Final Outcome
On Thursday, police announced that the suspect was found dead from a self-inflicted gunshot wound, nearly 24 hours after John’s tip. The case closed, ending months of uncertainty for the Providence community. The FBI had offered a $50,000 reward for information about the Brown shooting, and Ted Docks, the special agent in charge, said it would be logical for the tipster to be entitled to it. John’s anonymous contribution underscores the critical role of community witnesses in solving violent crimes, even as the full story of the suspect’s motives remains unclear.
Key Takeaways
- John’s anonymous tip on Dec. 16 provided the missing link that identified Brown University shooter Claudio Neves Valente.
- The tip led police to a grey Nissan rental, which helped confirm the suspect’s vehicle and location.
- The suspect was found dead from a self-inflicted gunshot wound, closing the case nearly 24 hours after the tip.
The Providence community now has closure, but the events that led to the shootings and the suspect’s motives still raise questions. John’s actions demonstrate how a single witness can alter the course of an investigation and bring justice to victims and their families.
