Dr Sam Shepphard had it all – a brilliant career, a beautiful wife, a young family, and a gorgeous house overlooking Lake Eerie. Then, on Independence Day 1954, his dream life came tumbling down. A bushy-haired burglar broke into the Sheppard residence and beat pregnant Marilyn Sheppard to death while she slept. At least, that was Dr Sheppard's story, and he stuck to it. But the police and the courts were dubious – and the events of that summer night in Bay View, Ohio, would echo down the decades. The Psycho Killer team has been taking a fresh look at the evidence.
