What Comes Next

  1. After filing a complaint, a letter will be mailed within five (5) business days detailing whether COPA or the Chicago Police Department’s (CPD) Bureau of Internal Affairs (BIA) will be in charge of investigating the incident of police conduct. To learn about which cases are assigned to COPA or BIA, please visit our Investigative Process page.
  2. If COPA retains the case, you and other complainants or witnesses will be contacted by COPA about the complaint.
  3. After concluding our investigation, you and the involved CPD member(s) will receive letters from COPA reflecting our investigative finding(s), if any. If discipline or other actions are recommended, the case will then be reviewed by the CPD Superintendent and, if applicable, the Chicago Police Board as part of the review process.
  4. At the conclusion of the review process, you and the involved CPD member(s) will receive a letter reflecting the final findings and the final action taken in the case.

Your Experience

Upon submission of a complaint, you may receive a text message at the phone number provided asking you to complete a survey about your experience with COPA. This message is sent by an independent company contracted by COPA and your response is confidential. Participation in the survey or any results submitted will not impact any investigation into your complaint. Your responses are very important to us and will be used to train members of COPA staff who interact with complainants, their families and other representatives.
