CONCORD — Without debate, the state Executive Council rejected a bid by Robert McLaughlin, 83, for a hearing on his request for a pardon of his first-degree murder conviction for the 1988 slaying of Robert Cushing Sr. of Hampton.

State prosecutors said McLaughlin, an 18-year veteran of the Hampton Police Department, was acting on a grudge on June 1, 1988, when he came to Cushing’s front door and fatally shot him.
