Closing arguments expected Friday in ex-officer’s manslaughter trial

Closing arguments are expected Friday in the trial of Cooper Ouellette, accused of running over and killing his 17-year-old girlfriend, Sophie Ringquist, in Connecticut in 2023. Prosecutors say Ouellette accelerated as the truck door opened while Ringquist was recording a video; the defense argues her death was an accident after she fell or jumped from the truck. Ouellette has pleaded not guilty to first-degree manslaughter and delivering alcohol to a minor, and jurors are expected to begin deliberating after the arguments.
