Investigations
The Investigations division is headed by the Commander of Operations and has two full-time,
plain-clothes detectives assigned to the unit.  One of the investigator's positions rotates every two
years to give members of the patrol division an opportunity to gain in-depth knowledge and
experience in criminal investigations.

There are different ways for an investigator to become involved in a case.  After a uniformed officer
has taken the initial complaint and they have completed the preliminary case work, the report will be
forwarded to the unit for additional follow-up.  Some of the criteria used to determine follow-up for the
unit include: suspect information, witness statements, vehicle information, physical evidence, crime
patterns and method of operation.  The cases are reviewed by the Command Staff and forwarded to
the unit for follow-up.  The cases may be closed administratively if no other information can be
gathered; the cases may result in an arrest and the paperwork is completed for prosecution.

The Investigations division also works closely through cooperative efforts with other municipal,
county, state, and federal agencies to help clear serious crimes of mutual concern.
