The Saint Paul Police Department investigates crimes that involve the use of firearms. In many of these investigations evidence is recovered, including discharged cartridge cases (DCCs).  Discharged cartridge cases are analyzed by the Integrated Ballistic Identification System (IBIS), managed by the National Integrated Ballistic Information Network (NIBIN), to investigate different incidents that may have been committed with the same firearm regardless of location and jurisdiction.

This policy provides the standard operating procedure for test firing firearms recovered by the department as potential evidence for the purpose of retrieving a set of known DCCs that can be entered into the IBIS/NIBIN database. The intent of the department is to test fire every firearm that produces DCCs that are suitable for entry into the IBIS/NIBIN database.  For purposes of this policy, the forensic services unit (FSU) is the authority responsible for coordinating and/or conducting test fires.

  1. SPPD personnel assigned to the gun and gang unit or forensic services unit (FSU) that are authorized by the unit commander or forensic laboratory manager may conduct a test fire for evidentiary purposes.
  2. Every test fire must be performed under the direction of a gun and gang unit sergeant, authorized FSU technician/scientist, and/or a current department firearms safety instructor.  At a minimum, one of the two must have current armorer training or be a current use-of-force instructor.
  3. The FSU will automatically collect DNA from every firearm prior to conducting a test fire.
  4. After the firearm has been processed for DNA, the firearm will be test fired.
  5. A minimum of two authorized FSU or gun and gang unit personnel will take the firearm to an approved SPPD gun range or the test fire area designated in the sub-basement of headquarters and ensure that all department range policies are followed.
  6. Gloves will be worn when handling the firearms.
  7. Each firearm will be inspected by an armorer and/or current department firearms safety instructor to assess the functionality of the firearm so that it may be fired safely.  
  8. Two cartridges will be placed in the firearm magazine which will be safely seated into the firearm.
  9. Two rounds will be fired downrange (if at a range) or into the bullet trap located in the test fire area.
  10. Both known DCCs will be placed into a "Test Fire Evidence" envelope that is marked with the case number, unique item number, and the identifying information of the firearm.
  11. The firearm will be inspected to ensure it is unloaded and repackaged in the gun box.
  12. The firearm will be returned to the property room or retained in the forensic services unit for further processing.
  13. The known DCC evidence will be entered into Evidence Manager according to current property and evidence procedures and will be retained in the FSU for NIBIN entry.
  1. The person conducting the test fire will write a supplemental report documenting how the test fire was performed, who performed it and what the results were.
  2. The FSU will enter DCCs into the IBIS/NIBIN database and will write a supplemental report documenting the entry.
  3. NIBIN search results are returned to the person that entered the search in IBIS and the office assistant for the FSU.
  4. Any potential associations are disseminated to the assigned investigator(s) and are documented in a supplemental report.  Searches with no potential associations are documented on the IBIS spreadsheet that is accessible by FSU and the gun and gang unit.

Circumstances where a firearm may not be test fired include, but are not limited to:

  • Loose or bulging barrel
  • Bore obstruction
  • Rusted or corroded components
  • Broken or missing parts
  • Loose or missing screws
  • Alterations or adaptations either intentionally done or through wear
  • Unknown caliber of the firearm
  • Any other condition where the armorer does not feel comfortable firing the weapon

Firearms to be test fired will not have any of the components of the weapon taken apart or modified to make the weapon serviceable. It must be fired "as is" or not fired at all. If a firearm is deemed to be not suitable for test firing the case investigator will be notified and it will be the investigators decision whether the firearm is sent to the BCA.

Firearm Retention Schedule

When determining the retention schedule for firearms submitted for test fires, investigators should follow the Ramsey County Evidence Retention Policy (RCERP) for charged cases.

For uncharged cases, the department's general orders and procedures supersede the RCERP in the following ways:

  1. When there are no investigative leads generated from the entry of the test fired DCC into IBIS/NIBIN, or other testing that is appropriate under the circumstances and authorized by the department, the firearm will be returned to a rightful, legitimate owner if possible. If the firearm becomes abandoned or unclaimed property, it will be processed for disposition according to the department's abandoned and unclaimed property procedures consistent with Saint Paul Legislative Code chapter 14.
  1. When lead(s) are generated from the test fired DCC or other forensic testing, the firearm may be retained for up to 12 months from the date of the IBIS/NIBIN submission to allow investigators time to follow up on the new lead(s). If no additional leads are developed, the firearm will be returned to a rightful, legitimate owner if possible. If the firearm becomes abandoned or unclaimed property, it will be processed for disposition according to the department's abandoned and unclaimed property procedures consistent with Saint Paul Legislative Code chapter 14.

Gun Return Request Checklist

The gun unit utilizes a Gun Return Request Checklist (GRRC) to facilitate the return of firearms no longer held for evidence to a rightful, legitimate owner. The GRRC ensures all processing for the firearm has been completed, and that the owner is able to legally possess a firearm.  A "rightful, legitimate owner" is an owner who can prove that they are the current owner of the firearm in custody.  A gun unit investigator will also attempt to locate an owner using eTrace, RMS, or other investigative methods available to the best of the investigator's abilities.  The investigator will write an RMS report documenting the methods used to locate or identify an owner in RMS, and the findings.

  1. If an owner can be identified, the investigator will send a letter by U.S. Mail to the address of record.  The letter will detail the process and time frame to file a gun return application.  If approved, the investigator, using the GRRC, will authorize the return of the firearm in accordance with the retention time frames in this policy. If not approved to return to owner, the investigator will send a letter to the address of record, detailing the circumstances and including instructions for follow-up. If an identified owner does not claim the firearm, the firearm will be processed for disposition according to the department's abandoned and unclaimed property procedures consistent with Saint Paul Legislative Code chapter 14.

  2. When no owner of a firearm is able to be located, the department will process the firearm for disposition according to its abandoned and unclaimed property procedures consistent with Saint Paul Legislative Code chapter 14.

  3. On the rare occasion when an owner comes forward after a firearm has been dispositioned without notice to the owner, the investigator will refer the owner to Saint Paul City Risk Management.

Firearms that are not evidence

Firearms that are contraband or forfeited will be destroyed. Firearms that are abandoned or unclaimed, and that are not evidence, contraband or forfeited, will be processed for disposition according to Saint Paul Legislative Code chapter 14.
