Police charged a teenage boy with the murder of a University of Chicago graduate student this morning.

 Eric Walker, 16, of the 7700 block of South Marshfield Ave. told detectives he was involved in the killing of  Amadou Cisse, a police spokesman said.

Cisse was shot in the chest in the early morning of Nov. 19, in front of his off-campus apartment at 61st Street and Ellis Avenue.

Walker is being charged as an adult with first-degree murder. He also faces robbery charges, police said.

Police said Walker was caught with help from witnesses and video surveillance cameras which captured images of the get-away car.

Cisse was earning his doctorate in chemistry and was scheduled to graduate next month. The university will award him the degree posthumously.

There will be a memorial for Cisse Friday at 3 p.m. at the Bond Chapel at 1050 E. 59th Street at the U of C Campus.

The university also set up a memorial fund for Cisse. Donations may be sent to the Amadou Cisse Family Support Fund, c/o University of Chicago Bursar, 5801 S. Ellis Ave., Chicago, IL 60637.
