On a misty October evening in 1998, a 14-year-old girl arrived at her cousins Oregon home to babysit her twins. But when she returned from a night out, the evening before Halloween, she found her cousin gone. While her twins were safe in their cribs, her teenage cousin was missing - with no signs of a struggle or forced entry into the house. Although they had already been speculating foul play, when her remains were eventually found amongst thick woodland, her case was officially considered a homicide. This is the story of Stephanie Condon.
