CHICAGO — A 21-year-old Chicago resident is charged with transmitting a threat in interstate commerce.

A federal criminal complaint said that Jabari R. Dean threatened on a social media website to kill 16 white male students or staff at the University of Chicago.

The threat came days after a video was released showing Officer Jason Van Dyke shooting 17-year-old Laquan McDonald 16 times. It prompted several days of protests in the city.

The complaint says an FBI officer wasn’t able to see threat that was posted on Nov. 28, but reviewed a screenshot of it provided by the person who reported the threat.

Authorities said Dean posted online that he would “execute approximately … 16 white male students and or staff, which is the same number of time (sic) McDonald was killed.”

The complaint also said Dean admitted to FBI agents that he posted the threat and took it down shortly after.
