Bangor police Detective Capt. Clifton E. Sloane... told the Bangor Daily News in a March 1971 interview that he knew, beyond any reasonable doubt, who the killer was, but didn’t have the physical evidence to convict him in a court of law.
Investigators had interviewed hundreds of people and within a few days of the homicide, had narrowed the list of possible suspects to a handful and finally to one, a male guest at the hotel, Sloane said. The suspect, who was seen leaving by the back door, according to information provided to MacDonald’s family, is now dead.
The case is still open because there is no statute of limitations with murder, Stokes said. Even so, Bangor police have the investigation listed as dormant and does not have an investigator assigned to the case.
