serial killer investigationn 300 words

 
One of the biggest challenges in serial killer investigation has always been the challenge of recognizing that different victims may be connected to the same killer. In the wake of the Bundy cast, the FBI created the ViCAP.

Describe the ViCAP program and why it was inspired by the Bundy case in particular. Is this an effective resource? What type of serial killer in particular would a program like ViCAP be used for?
Describe the Combined DNA Index System CODIS and answer the same questions as above.
Discuss why it is difficult for law enforcement agencies to work together when they are faced with a case such as that of an active serial killer. Should local law enforcement turn the case over to the FBI in these situations? Why might a Sheriff, in particular, be less willing to turn over control?
