Rodney Kyles Jr., 19, was fatally stabbed on September 3, 2011, on the 1100 block of West Wrightwood Avenue in Chicago’s Lincoln Park neighborhood after leaving a party. A Roosevelt University philosophy student and aspiring musician, Kyles was remembered as well liked on campus and passionate about music.

Controversy followed his death when a blunt tweet posted shortly before the killing was widely quoted in media reports. Students and the Black Student Union at DePaul criticized coverage that they said used that tweet to frame Kyles’ character and overshadow his life and achievements.

Anyone who knew Rodney at Roosevelt, or who was in Lincoln Park that night and can help fill gaps in the timeline, is asked to come forward with information.
