hello and welcome to dateline extra. i m craig mellin. this story involves a young mother who disappeared one morning. her husband said she went for a run and never came home. it was a puzzling case. it happened in a safe suburban neighborhood, the kind of place where crime is unexpected. even more unexpected, the tiny clue buried in a computer that unlocked a mystery. here s keith morrison. nothing about that morning made any sense. it all seemed like such a bad nightmare. this doesn t happen in our happy little world. it was a saturday morning in july 2008. the happy little world a sweet and leafy suburb of raleigh, north carolina called cary. the sort of place a young family would aspire to. if you were someone like hannah pritchard, for example. there s always lots of friend making going on through someone
