A Burlington man accused of double murder made his initial court appearance Monday morning at Superior Court in Bangor. 31-year-old Nathaneal Nightingale is charged with the murders of a husband and wife in Webster Plantation last month. According to court documents, Nightingale shot Michael and Valerie Miller, both 47, in the head during a robbery attempt. Nightingale admitted to police he shot the couple and provided details of the crime. Nightingale was arrested shortly after midnight Saturday at his family’s residence on Fogg Lane in Burlington.The bodies of Michael Miller and his wife Valerie were discovered in late November in their home on the Tucker Ridge Road.Jeffrey Silverstein says he expects to be retained as counsel for Nightingale. “He understands what the charges are,” says Silverstein, “he’s very despondent over the situation. It appears as if he’s made some statements acknowledging some responsibility. To my knowledge this appears to be a horrible accident gone wrong and we intend that, over time, we will produce additional circumstances and hope to put this in to proper context.”Nightingale is due back in court January 22.
