Dr. Margaret Kilcoyne, a cardiologist, was last seen on January 26, 1980 at her secluded vacation home in Nantucket, MA. Dr. Kilcoyne, a physician, Columbia University researcher, and a native of Worcester, had gone to bed about 2200 hours the night before, but was missing from her bedroom when her brother went to awaken her that morning for church. Her bedclothes were on the bed, her shoes on the floor and her only coat in a closet. She left no explanation of why or where she had gone. Dr. Kilcoyne's car and bicycle were in her garage, and there was no indication she had been given a ride. She has not been heard from since. Days later, searchers who had covered the area previously found her passport, bank book, sandals, and a wallet containing a $100 bill neatly stacked in a clearing not far from the house. A clean blouse lay under a bush.
