There is a whole chapter on the case in “It’s Me, Edward Wayne Edwards, the Serial Killer You Never Heard of“, Chapter 25, starting page 223.
July 16, 1955, a post card was sent to Berkeley Police, in Edwards’ handwriting. The day after, Edwards contacted the San Francisco Examiner, and lead them to the body, planted across from Abbott’s cabin. He planted the body the day after police had searched. Further letters were sent.
Also in the book, page 238, is a letter dated April 24, 1995, from George T. Davis, Abbott’s lawyer, to Keith Walker who wrote a book about the case. Davis says he is convinced that Abbott did not commit the crime, and the book is accurate.
Book description ( via Amazon ):
How could a man be guilty of kidnaping and killing a 14-yr.-old school girl while on a fishing trip miles away when she disappeared? The district attorney claimed the suspect was a vicious sex killer who stalked the victim – and kept her possessions as a fetish. But Burton Abbott said he was 175 miles away when young, pretty Stephanie Bryan was last seen near her Berkeley, CA, home. And he had witnesses to prove it. Keith Walker’s compelling story asks: Did Abbott leave a “trail of corn”, showing evidence of his implication, as the district attorney claimed, or did someone else leave the “trail of corn”, perhaps purposely? A phone call with only two minutes to spare, a mother’s anguished cries, soil on boots nine inches down in the grave, human fingers protruding from under a trunk lid – these are some of the strange ingredients that went into this fascinating story. Burton Abbott was a tubercular ex-GI student at the University of California in Berkeley, CA, when Stephanie disappeared on her way home from school on April 28, 1955. Investigation showed Abbott made a trip to the family cabin on the day the girl disappeared. Later, Stephanie’s remains were found in a grisly grave 339 feet up a steep hillside above the cabin. But Abbott flatly denied any implication in the girl’s death. He said he was the victim of cruel hoax, a ruthless district attorney who based his case on suppositions and innuendoes, and a biased judge. The case was a controversial one, with almost everyone divided on whether he committed the crime. There was only circumstantial evidence to implicate him. Puzzling twists of the story produced blazing headlines month after month in California newspapers. Keith Walker, a newspaperman at the time, spent 35 years researching and writing this book. He has produced a powerful story of intrigue, suspense, drama, grief, conflict and human emotions. He has used his reporter’s skills to bring you the full scope of this bizarre, compelling story.
