Michigan AG Rules Trooper Acted in Self-Defense in Fatal Detroit Traffic Stop

The Mason family contests the state review, seeking a special prosecutor plus additional records.

Overview

  • State prosecutors said Trooper Justin Cope will not face charges after a review found his use of deadly force was lawful self-defense.
  • Michigan State Police released body‑worn and dashcam video that officials say aligns with the findings in the attorney general’s report.
  • The review says a speeding stop escalated when a concealed revolver fell as Stephen Wangara-Mason exited his vehicle, leading to a struggle in which Mason shot the trooper three times.
  • Investigators reported two shots were stopped by Cope’s vest and a third struck his clavicle; he underwent surgery and was released from the hospital the next day.
  • The report notes Cope immediately called for EMS, concluded Mason was immediately deceased with EMS arriving in six minutes, while the family’s attorney seeks a special prosecutor and additional records and alleges officers failed to render prompt aid.
