BANGOR — A Maine man convicted of murder and manslaughter in the killings of a husband and wife in Webster Plantation has been sentenced to 40 years in prison.

Nathaneal Nightingale of Burlington was convicted of manslaughter in the death of Michael Miller and murder in the death of Michael’s wife Valerie. WABI-TV reported today that Nightingale was sentenced to 40 years for murder with a concurrent 15 years for manslaughter.

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