In May 1983, a quiet stretch of road outside Springfield, Oregon, became the setting for one of America’s most disturbing murder cases . Diane Downs, a 27-year-old divorced postal worker, arrived at McKenzie-Willamette Hospital late at night with a gunshot wound to her left arm and her three young children bleeding in the back of her car. Her seven-year-old daughter Cheryl was pronounced dead shortly after arrival. Her other children - Christie, eight, and Danny, three - were critically injured.
