CNN’s Drew Griffin has been following the case of a brutal killing allegedly fueled by racism.

Deryl Dedmon, a 19 –year old teenager from Brandon, Mississippi, faces charges of capital murder and a hate crime in the death of James Craig Anderson, stemming from an incident involving a gang of white teenagers who attacked Anderson early in the morning of June 26. Dedmon has pled not guilty, and in court his attorney said he saw nothing in the incident that suggests racism.
