The C.I.S. is responsible for Investigating the variety of crimes which can occur within ISPD Jurisdiction.  These cases can range from Burglary and Fraud, up to and including Death Investigations.  Patrol Officers are given the opportunity to work most cases in their entirety, meaning from the time they receive the call, until the closing or resolution of the case.  However, cases requiring a more in depth Investigation are forwarded to the Criminal Investigation Division.
