Jurors will return to a Rockland courtroom on Friday to try and reach a verdict in the trial of a Maine lobsterman.Vance Bunker is accused of shooting a fellow lobsterman in a feud over lobster traps.The 68-year-old is charged with elevated aggravated assault, among other charges, for shooting 44-year-old Christopher Young in the neck on a wharf on Matinicus Island last July.Bunker’s daughter, Janan Miller, is also on trial for reckless conduct for her role in the shooting.Bunker testified on Thursday that he shot Young because he felt he and his daughter’s life was at risk during a struggle over a shotgun.The prosecution didn’t see it that way. “His brother almost had been shot,” Said District Attorney Geoffrey Rushlau. “It may take a moment for him to realize Weston hasn’t been shot and while he’s looking at Weston he’s shot. He’s not lounging at Vance Bunker. He’s not looking at Vance Bunker. There’s nothing justified about that.” “Imagine that father standing on a wharf with these 2 men charging his daughter, despite she has a gun, and to start struggling with her over that gun. Imagine what’s going through that father’s mind at that point,” Argued Bunker’s attorney, Philip Cohen. “The question isn’t what type of father would pull the trigger. The real question is what type of father wouldn’t pull the trigger?”Jurors deliberated for three hours before being sent home Thursday night.They’ll re-convene at 8:30 Friday morning.
