Authorities continue to search for the shooter who attacked Brown University on December 13, 2025.
The incident killed two students and injured nine others.
Police describe the suspect as about 5 feet 8 inches tall, with a stocky build, wearing a two-tone jacket and dark clothing.
They released new surveillance footage to help identify the person.
Amid this manhunt, social media users focus on Mustapha Kharbouch, a Brown University student.
Kharbouch studies international relations and anthropology.
He describes himself as a third-generation Palestinian refugee.
He serves on the board of the university’s Arab Society and works with the Global Brown Center.
He also explores topics like queer and Palestinian identities. In 2025, he interned at the Center for Human Rights.
Speculation started when Brown University removed his profiles from their websites.
His X account got deleted, and his LinkedIn page turned private.
Users on platforms like X share theories that his walk matches the suspect in the footage.
Some suggest political motives tied to campus tensions over Gaza.
However, officials have not named Kharbouch as a suspect.
The FBI and police say the shooter remains at large and armed.
They detained a person of interest over the weekend but released them after evidence cleared them.
Major U.S. news outlets have not linked him to the case, with talk mostly on social media and some international reports.
A separate shooting killed an MIT professor in December 2025, but investigators see no clear connection to the Brown incident.
The manhunt goes on, with police asking the public for tips.
