Filing a Complaint Against an NPS Law Enforcement Officer

When filing a complaint, please include as much of the following information as possible to help ensure that a thorough investigation is conducted:

• Describe the incident — include the date, time, location, and name of the NPS unit.
• The law enforcement officer or special agent’s name, badge number, and description.
• Identification of any witnesses — include name(s), address(es), and telephone number(s).
• Vehicle description — include the plate number and state.
• Reminder: OPR does not handle and will not respond to any issues that are not related to NPS law enforcement officers.

The Complaint Process

When a complaint is received, OPR sends a letter notifying the complainant that the complaint has been received and assigned for investigation.

The investigator assigned to the case will conduct a thorough investigation, to include an interview of the involved employee and any witnesses that have been identified. The investigating official may contact the complainant for additional information or to clarify information already provided. The responsible manager for the investigation will make a determination concerning the complaint based upon the proven facts. The decision will be one of the following six findings:

• Unfounded — The allegation is false or not factual.

• Exonerated — The actions were lawful and within policy.

• Not Sustained — The complaint can be neither proved nor disproved.

• Sustained — There is sufficient evidence to justify a reasonable conclusion of misconduct.

• Other — There is an administrative or legal justification for the incident.

• Suspended — All reasonable investigative leads are exhausted and sufficient information is not available to proceed.

The complainant will be notified by letter at the conclusion of the investigation.

If an allegation is sustained, appropriate disciplinary action will be taken against the affected employee. In accordance with the Privacy Act, information on the specific discipline imposed on an employee is not released.
