Episode 38 of "Criminal Minds"
s02e16 Fear and Loathing

The BAU team travels to an upscale New York neighborhood to hunt a serial killer they fear is racially motivated. With community leaders in an affluent, predominately white New York suburb fearing the worst, Gideon and the rest of the BAU team arrive to investigate the murders of young African American teenagers who are found beaten and strangled. With little to go on and evidence that continually leads to dead ends, the team must work quickly to determine if the crimes are the result of a racially-charged serial killer before the potential fall-out from the crimes leads to even bigger problems.
