On Dec. 14, 1991, 16-year-old honor student Sarah Yarborough was on her way to drill team practice at Federal Way High School outside Seattle, Wash. She never made it. She was found murdered just a hundred yards away from her car on the school's campus. Correspondent Natalie Morales speaks to key people who were involved in bringing Yarborough's killer to justice, including the first television interviews with Sarah's family and friends, and a woman who had been attacked by the same man years earlier.
