Immediate Changes in Evidence Intake

Delivering exceptional law enforcement services for a safer Minnesota is the mission of the BCA.  With the ongoing spread of COVID-19 and the incredible speed at which things are changing around us, we are continually adapting our operations and business.  We will continue to provide services at the BCA facilities and in the field.  Our goal is to continue to provide these vital services while at the same time ensuring the health of our partners and our employees.  Please see below for evidence submission and pick up guidelines.  These guidelines will be in effect immediately and will be reevaluated as necessary.


Evidence submissions brought to the BCA FSS St. Paul, Bemidji, or St. Cloud locations can continue to be dropped off, but law enforcement representatives will not stay during the duration of the intake process.  Please see Intake Instructions for further details.

  • Mailed submissions (if appropriate) are encouraged.
  • Be sure all appropriate submission paperwork is filled out completely prior to drop off.  Submission paperwork can be found on our Evidence Submission page.
  • Please call or email prior to drop off with any submission questions.
  • Evidence will receive a time/date stamp by evidence intake personnel during drop off and will be entered as part of the chain of custody.
  • A receipt will be generated after submission and available as usual.
  • Missing information in paperwork will delay the submission.  If we are unable to reach the contact provided, evidence may be returned to the agency.
  • Evidence submitted outside BCA policy will be returned or reported with no exams to be completed.
  • Please call ahead for cases with greater than 10 items to make an appointment. 


It is requested that evidence pick up be suspended unless necessary.  If you need to pick up evidence, please call ahead so we can get your evidence ready.  Another option would be for us to return your evidence by courier service.

We are closely following the Centers for Disease Control's (CDC) guidelines and recommendations on the steps we can all take to prevent the spread of the virus.

Thank you for your understanding and cooperation as we navigate through these challenging times together.
