Synopsis:
Alan and Diane Johnson had a picture-perfect life, or so it seemed. They'd been together for 20 years and lived in a beautiful home on the outskirts of Sun Valley, Idaho. They treasured their close-knit family, which included two children, 21-year-old Matt and 16-year-old Sarah. But just after Labor Day weekend in 2003, that happy family life came to an abrupt end when Alan and Diane were brutally murdered in the bedroom of their home. Deborah Roberts reports on the horrific crime, how it could have happened and who might have done it.
