A gunman shot down two cousins on the West Side of Chicago last night in what appears to be a random act of violence.
Neither man survived.
Family members who witnessed the shooting have no idea why it happened.
"We saw him walking up the block, then he stopped a few houses down, turned and walked away," said Sharnia Goodman, who was Day's girlfriend. "About ten minutes later he came back, the shooting started and everybody tried to run."
Williams, a student the University of Illinois in Urbana-Champaign, was home for the weekend to get an outfit to wear to a homecoming dance at the school, Lanre Sanya, who is Percy's uncle and Tyrone's cousin told the Tribune.
Day attended DeVry University, where he was in a program to get his high school diploma and an associate's degree.
Police have not made any arrests and have no motive for the shooting.
