If a concern of policy, procedure, or any other issue is brought forward, we will listen to your concern.

How Investigations Work

Complaints of misconduct will be thoroughly investigated. This investigation generally includes:

  • An interview with the person making the complaint
  • An interview with any witnesses
  • An interview with the involved employee
  • A review of all reports, tape recordings or other evidence

The investigative report is forwarded to the Chief of Police who reviews the investigation and arrives at a final determination. Determinations are:

  • Substantiated - The allegation is supported by sufficient evidence
  • Unsubstantiated - There was insufficient evidence to prove or disprove the allegation
  • Proper Action - The incident occurred, but the employee acted lawfully and properly
  • Unfounded - The allegation is false or not factual
  • Misconduct not Based on Complaint - Substantiated misconduct, not alleged in the complaint, but disclosed by the investigation
  • Exceptionally Cleared - The accused employee is no longer a member of the department at the conclusion of the investigation.
