Prosecutors have charged a 17-year-old Chicago resident with three counts of armed robbery and one count of aggravated discharge of a firearm in a series of robberies near the University of Chicago last week, the Chicago Tribune reported today.

The attacks ended in the shooting death of Amadou Cisse, a graduate student, who was killed while walking to his off-campus apartment. The university drew criticism for its handling of the incidents.

The police believe that the suspect, Demetrius Warren, 17, was the gunman in the attacks. None of the charges, however, were directly related to Mr. Cisse’s slaying, which remains under investigation.

Earlier this week, prosecutors charged Eric Walker, 16, with first-degree murder, among other felonies. —Eric Hoover
