Sarah Neal (6 of Diamonds, Nebraska)

16-year-old Sarah was not your typical teen. She was a multisport high school athlete who participated in basketball, softball, and track. She was a pretty darn good chess player, too. But in June of 2005, somebody took all that Sarah loved away from her. And they took Sarah away from everyone who loved her. 19 years later, the police are still trying to catch her killer, and they need your help.
