Police: Robbery motive in Dunwoody slaying

Police said Wednesday that robbery was the motive in the slaying of a man at a Dunwoody apartment complex last week.

Christopher Williams, 20, of Stone Mountain was arrested Tuesday and charged with murder in the slaying of Roberto Calderon-Guzman, 28, Dunwoody police Sgt. Mike Carlson said. Calderon-Guzman was shot inside an apartment at the Peachtree Place complex on Peachtree Place Parkway just before 12:30 a.m. Friday.

Carlson said Williams was targeting victims through backpage.com, a classified advertising website similar to CraigsList.
