What to know about the search for the Brown University shooting suspect

Police had detained the man at a Rhode Island hotel. State Attorney General Peter Neronha acknowledged the seriousness of the situation, saying, “We have a murderer out there.”

On Monday, Providence police released three videos of the man they believe carried out the attack that show him wearing a mask and a dark two-tone jacket. The footage from about two hours before the shooting provided the clearest images yet of the suspect.

The FBI said the man is about 5-feet-8, with a stocky build. The agency offered a $50,000 reward for information leading to the identification, arrest and conviction of the person responsible.

A busy time on campus

The shooting occurred as students were taking final exams.

The gunman opened fire inside a classroom in the engineering building, getting off more than 40 rounds from a 9 mm handgun, a law enforcement official told The Associated Press. Two handguns were recovered when the person of interest was taken into custody and authorities also found two loaded 30-round magazines, said the official, who was not authorized to discuss the investigation publicly and spoke to AP on the condition of anonymity.

The students who died were MukhammadAziz Umurzokov, an 18-year-old freshman from Brandermill, Virginia, and Ella Cook, a 19-year-old sophomore from a suburb of Birmingham, Alabama. Umurzokov was an aspiring neurosurgeon and Cook was a student leader of Brown University’s campus Republicans. They were in a study group preparing for an economics final.

One of the nine wounded students has been released from the hospital, university President Christina Paxson said Sunday. Seven others were in critical but stable condition, and one was in critical condition.

Durham Academy, a private K-12 school in Durham, North Carolina, confirmed that a recent graduate, Kendall Turner, was critically wounded and that her parents were with her.

Another wounded student, 18-year-old freshman Spencer Yang of New York City, told the New York Times and the Brown Daily Herald from a hospital bed that there was a mad scramble after the gunman entered the room where he and the other students were studying for finals. Many students ran toward the front of the room, but Yang said he wound up on the ground between some seats and was shot in the leg.

Investigators were not immediately sure how the shooter got inside the classroom, which is on the first floor of a seven-story complex that houses the engineering school and physics department.

New efforts to find the shooter

Authorities asked neighborhood residents and businesses for surveillance video that might help identify the attacker. They said Sunday that one reason they lacked video of the shooter was because Brown's engineering building doesn't have many cameras.

Law enforcement on Monday appeared to still be performing the most basic of investigative tasks: tracing the suspect’s movements in the minutes after the attack and searching for physical evidence near the crime scene.

Mayor Brett Smiley said there have been no credible threats of further violence since the shooting, and the city's schools were open Monday.

Brown student survives a second school shooting

Brown University junior Mia Tretta was 15 years old when she was shot in the abdomen during a mass shooting at Saugus High School in Santa Clarita, California. Two students were killed, and she and two others were wounded.

On Saturday, Tretta was studying in her dorm with a friend when the first message arrived warning of an emergency at the university’s engineering building. As more alerts poured in urging people to remain locked down and stay away from windows, the familiarity of the language made clear what she had feared.

“No one should ever have to go through one shooting, let alone two,” Tretta told the AP by phone Sunday.

A community grieves

On Sunday evening, city leaders, residents and others gathered at a park to honor the victims. The event originally was scheduled as a Christmas tree and Hanukkah menorah lighting.

Brown, the seventh-oldest higher education institution in the U.S., is one of the nation’s most prestigious colleges, with roughly 7,300 undergraduates and more than 3,000 graduate students. The school canceled all remaining classes and exams for the semester.
