CHICAGO — An online threat against the University of Chicago that led the school to cancel all classes and activities on Monday appears to have been motivated by the fatal shooting of a black teenager by a Chicago officer in 2014, federal authorities said.
Jabari R. Dean, 21, of Chicago, threatened to kill 16 white male students or staff at the school on Chicago’s South Side, according to the criminal complaint. Dean was arrested Monday morning and is charged with transmitting a threat in interstate commerce.

The threat was posted Saturday, just days after the city released a video of Officer Jason Van Dyke, who is white, shooting 17-year-old Laquan McDonald, who was black, 16 times. The video sparked days of protests in Chicago, including one that blocked off part of Michigan Avenue in the downtown shopping district known as the Magnificent Mile on Black Friday.
Van Dyke is charged with first-degree murder, and his bond was set for $1.5 million on Monday. Van Dyke’s attorney said he was hopeful his client could be released in the “very near future.”
Authorities said Dean posted online from a phone that he would “execute approximately … 16 white male students and or staff, which is the same number of time (sic) McDonald was killed” and “will die killing any number of white policemen that I can in the process.”
The criminal complaint, released by the U.S. attorney’s office in Chicago, said someone tipped the FBI on Sunday to a threat that was posted on a social media website. The FBI was unable to find the threat online, and was provided a screenshot by the person who reported the threat. That led them to Dean, who admitted to FBI agents that he posted the threat and took it down shortly after, the complaint said.
The University of Illinois at Chicago said earlier Monday that one of its students who lives off-campus was the person who was arrested, but the complaint did not say whether Dean was a student there.
The University of Chicago, where President Barack Obama taught law, first alerted students and staff Sunday night about a threat that mentioned the quad, a popular gathering place, and 10 a.m. Monday.
The University of Chicago statement urged faculty, students and non-essential staff to stay away from the Hyde Park campus through midnight Monday and told students in college housing to stay indoors. The cancellations affected more than 30,000 people, though the University of Chicago Medical Center was open to patients.
The normally bustling campus was largely quiet Monday morning as Chicago Police Department and campus security vehicles patrolled streets. Security staff in yellow jackets stood on campus walkways, including the quad that was mentioned in the threat. The time mentioned in the threat came and went without incident.
The university had said the decision to close was taken following “recent tragic events” at other campuses nationwide. On Oct. 1 at Umpqua Community College in Roseburg, Oregon, a gunman opened fire and killed nine people. Other shootings have happened in Arizona and Tennessee.
