BANGOR — Jurors have convicted a 32-year-old man in the shooting deaths of a husband and wife in their northern Maine home.

Nathaneal Nightingale told police in a confession played for jurors that he went to the victims’ home in Webster Plantation to pawn his stepfather’s handgun and accidentally shot Michael Miller Sr. on Nov. 28, 2009. He said he then shot Valerie Miller out of “desperation.” Both died from gunshot wounds to the head.

Jurors on Tuesday found Nightingale guilty of manslaughter in Michael Miller’s death and murder in Valerie Miller’s death.

The Bangor Daily News says testimony during the trial indicated Miller sold bootleg cigarettes, ran an unlicensed pawn shop and sold prescription narcotics from his home.
