Circumstances of Disappearance
Eaton was last seen on May 17, 1975. A sophomore at Penncrest High School, "Whizzie'' stayed at home on Mocassin Lane to sunbathe on the roof outside her bedroom window while while her parents and brother went to play golf at the country club.
When the family returned home about 7 p.m., they found Wendy's bathing suit on her bed.
Several neighbors last saw her walking to the intersection of Indian Lane and Media Station Road, three blocks from her home in the Indian Trails development, about 3:10 p.m. The family suspects she was on her way to Media to buy her brother a birthday gift.
Bloodhounds tracked her movement to the intersection of Indian Lane and Media Station Road, where she was last seen. But no further trace of her was ever found.
Wendy's disappearance coincided with the slayings of several other girls whose remains were found in the Tinicum Marsh area, but no evidence has ever been found that would link Wendy to those victims.
Authorities said that Wendy was a girl very unlikely to have run away on her own.
She planned to attend a singing group rehearsal at their church on the night she vanished. Her relatives stated that Eaton would not have missed the rehearsal.
