Ellen was a young girl who seemed to have it all - a fiance who loved her, a chic apartment in Philadelphia's Manayunk neighborhood, and a gorgeous smile. What could have gone wrong to make her want to end it all? Listen now to find out and sound off in the comments - did Ellen kill herself or have the most advanced assailant of all time, capable of murder without a trace?
