A Cook County jury has convicted a man accused of being an accomplice in the 2007 murder of a University of Chicago doctoral student from Senegal.
Demetrius Warren was accused of gunning down 29-year-old chemist Amadou Cisse while carrying out a series of robberies that night near the university's campus.

The 21-year-old Warren was found guilty late Monday of first-degree murder, armed robbery and aggravated discharge of a firearm. His sentencing is scheduled to take in October.
In closing arguments, assistant state's attorney Mark Shlifka called Warren "doctor death."
A co-defendant, Eric Walker, testified against Warren in exchange for a 20-year sentence for armed robbery. Benjamin Williams and Jamal Bracey pleaded guilty to the murder last year. Williams was sentenced to 53 years in prison. Bracey received a 35-year term.
