A Massachusetts prosecutor demonstrated a police officer's firearm in court Thursday, reportedly pulling the trigger during an assault trial. The action was part of the prosecution's argument that the defendant, North Andover Police Officer Kelsey Fitzsimmons, had falsely testified that she did not aim her weapon at a colleague.

During proceedings in a Massachusetts courtroom, Prosecutor James Gubitose aimed Officer Fitzsimmons' pistol toward the front of the room and depressed its trigger. The weapon emitted an audible "click," which Gubitose presented as evidence to counter Fitzsimmons' testimony. He asserted that the 29-year-old officer had attempted to fire at fellow Officer Patrick Noonan during a June 2025 incident, but the firearm failed to discharge due to a jam.

Fitzsimmons is currently on trial for assault, stemming from the confrontation with Officer Noonan. The prosecutor's courtroom demonstration and subsequent argument directly challenged Fitzsimmons' account, where she reportedly denied pointing the pistol at Noonan. Gubitose contended that Fitzsimmons' testimony was untrue and sought to illustrate the sequence of events he alleged took place.

The incident at the center of the trial occurred in June 2025 at Fitzsimmons' residence. Officer Noonan, accompanied by two other officers, was present at the home to serve Fitzsimmons with a restraining order that her fiancé had sought against her. It was during this interaction that Fitzsimmons is alleged to have pointed her weapon at Officer Noonan, an action she denies. The trial continues as the court examines the events of that day and the credibility of the testimonies presented.
