Hours after the FBI and police said they detained a man in connection with the deadly attack at Brown University, he was released. What happened?

The FBI is offering a reward of up to $50,000 for information leading to the arrest and conviction of the person who carried out the deadly mass shooting at Brown University, as authorities seek a suspect after releasing a person of interest who was detained Sunday.

Authorities are still searching for the person responsible for the shooting. Police released a new video of a person of interest in the attack earlier Monday.

Mukhammad Aziz Umurzokov's sister, who called him "the smartest," recounts finding out about his death, and Ella Cook is remembered as "an incredible light" who could "lift up those around her."

"Instead of enjoying the first snowfall, we are mourning our classmates and friends," wrote another student on a TikTok video of a happy snow day at Brown from a previous year. "The Brown we knew, one of safety and security, was stolen from us," added the student in the caption.

As the investigation into the fatal shooting continued, MAGA conservatives pushed out unsubstantiated theories about the tragedy.

An aspiring neurosurgeon and a student leader of Brown University’s campus Republicans were in a study group preparing for an economics final, with the end of the semester in sight.

Students for Brown's Daily Herald worked around-the-clock this weekend providing live updates on Saturday's deadly shooting.
