Chicago police say they are searching for a person of interest who may be involved in the shooting death of Earl "Tony" Hughes, the older brother of Irish running back Robert Hughes.
The elder Hughes died of a single gunshot wound early Tuesday. On Wednesday, Robert Hughes was back on the practice field for the Irish.
Charlie Weis will take Hughes back to Chicago on Thursday to spend time with the family. It's expected that the majority of the team will be in Chicago for the funeral on Friday
