Criminal Investigations Unit

The Criminal Investigations Unit (CIU) is supervised by a detective sergeant, who is responsible for reviewing all incoming cases, making decisions on follow-up investigations and assigning cases to the detectives for investigation.

Mission Statement

The mission of the Criminal Investigations Unit (CIU) is to provide high quality criminal investigative support to the Paradise Valley Police Department by conducting timely and thorough criminal investigations using advanced investigative techniques, and through an efficient use of resources. Motivated only by a search for the truth, CIU detectives will search out and collect all available evidence surrounding each case to exonerate the innocent and substantiate the culpability of the guilty. As professional fact finders, CIU detectives will conduct systematic and methodical investigations to determine what findings the evidence supports and will not form conclusions in advance.

CIU detectives recognize their responsibilities to the community they serve and are committed to investigating all criminal allegations in an ethical and impartial manner with sensitivity toward the needs of victims and witnesses. CIU detectives are steadfast in their resolve and will mobilize all available resources to accomplish their mission, despite any obstacles, discouragement, or danger.
