She had been playing video games that night with her 8-year-old nephew, Zion Carr, and it emerged at trial that they left the doors open to vent smoke from hamburgers the boy burnt.He’d completed the police academy the year before and quit the force without speaking to investigators.But under questioning from prosecutors he acknowledged numerous errors, repeatedly conceding that actions he took before and after the shooting were “more bad police work.”Darch’s back was to the window when Dean shot, but she testified that he never mentioned seeing a gun before he pulled the trigger and didn’t say anything about the weapon as they rushed in to search the house.Zion testified that Jefferson took out her gun believing there was an intruder in the backyard, but he offered contradictory accounts of whether she pointed the pistol out the window.On the trial’s opening day, he testified that Jefferson always had the gun pointed down, but in an interview that was recorded soon after the shooting and played in court, Zion said she had pointed the weapon at the window."
