Brown University is calling on the public to stop engaging in “harmful” social media activity while investigators work to identify the gunman who killed two students on its campus Saturday afternoon.

Two students were killed and another nine people injured in the shooting at the Ivy League school on Saturday.

After determining that a man they had detained was not the killer, Rhode Island officials have searched for more evidence and released photos of a possible gunman.

Once we identify who this person is, I believe we’ll be able to locate them,” Rhode Island Attorney General Peter Neronha said of the person of interest in the deadly Brown University mass shooting.

Sunday’s men’s basketball game between USC and Brown has been canceled due to the impact of Saturday’s school shooting that took place on the Providence, Rhode Island, research university campus.

On Dec. 13, after a gunman opened fire at Brown University, killing two and injuring nine before evading capture, Trump posted on Truth Social that "the FBI is on the scene. The suspect is in custody." But about 20 minutes later, Trump posted an update: "The Brown University Police reversed their previous statement — The suspect is NOT in custody."

Brown University senior Phoebe Peus recalls the "devastating" loss of friend Ella Cook and explains she first heard about the shooting from friends, not the school.
