21.00.030     FOLLOW-UP INVESTIGATIONS                    (CALEA 42.2.2)


When a preliminary investigation cannot provide sufficient information to satisfactorily complete a case, a follow-up investigation may be necessary.  An Investigations Supervisor will assign and direct the follow-up investigation of a case and maintain a record of the cases to be investigated.  Case records will include the name of the assigned patrol officer, community services officer or detective, case disposition, and other pertinent information.


A follow-up investigation shall include:


v     Organization of investigation goals to facilitate identification and apprehension of the suspect(s)


v     Reviewing and analyzing reports prepared in the preliminary investigation phase


v     Conducting any additional interviews/interrogations that aid in the investigative process


v     Seeking additional information through discussion with other officers, use of informants or other contacts


v     Reviewing departmental records to locate supportive background information and criminal history to determine suspect involvement in other crimes 


v     Consulting outside agency resources such as civilian experts or a telephone company


v     Review of the results from laboratory examinations


v     Dissemination of information to outside agencies as appropriate


v     Planning, organizing, and conducting searches or recovery of items pertinent to the investigation including the collection of physical evidence


v     Preparing cases for filing with the City Prosecutor or King County Prosecutor's Office


v     Assisting the prosecution, i.e., acting as liaison to witnesses and others associated with court proceedings


v     Identifying and apprehending suspects not otherwise indicated in preliminary report


v     Associating suspects with unreported/previously reported crimes, and initiating the investigative process thereafter


Cases requiring follow-up investigation may include second contact with victims and witnesses as part of the investigative process.  Second contact should occur, when applicable, within 72 hours following the assignment of the case to an investigator.  When the case is closed, the victim will be contacted, by the investigator, and advised of the status of the case.
