He said the night before, his wife had gone upstairs to bed while he was asleep on the couch. When he went upstairs, he saw his wife covered in blood. He heard a noise and ran downstairs chasing after a 6’3’’ bushy haired man. The two struggled and Dr. Sheppard was choked unconscious. When police arrived, Marilynn was found with 35 wounds to the head and blood drenched the walls, door, and bed. Her face was almost unrecognizable. Sheppard served 10 years in prison before the US Supreme court rules that the trial had been tainted. The evidence was reexamined. Blood spatters and blood drops provided some of the most compelling evidence. Dr. Paul Kirk, an expert in blood analysis, determined the killer could not have been Sam because the attack was perpetrated by a left handed person. Dr. Sheppard was right handed.. ..
