Details of Disappearance

Peggy was last seen in Superior, Montana on July 4, 1979. She and her husband, Earl, had traveled from their home in Maple Valley, Washington to visit relatives in North Dakota, and they stopped at the Big Sky Motel in Superior on the way home.

Earl stated that he woke up in their room at 11:00 p.m. and Peggy was gone. Her purse, credit cards and travel bag were also missing. She has never been heard from again. Earl waited for nine days before reporting the disappearance to police; in the meantime, he tried to find Peggy by checking to see if she was with various friends and relatives.

The DeCoteaus had been having marital problems, and investigators believed at first that Peggy had left of her own accord. Her credit cards were never used after she went missing, however, and foul play is now suspected in her disappearance. Her case remains unsolved.
