Who Really Killed Jessica Rivertt?

AN: Thank you for reading if you choose to! This is my first attempt at a story created on my own. ~Sammi.

Once upon a time, I lived a wonderful live, had everything I'd ever wanted, until I was murdered. At least that's what everyone believes happened to me June 24th, 1986. They had captured my 'Murderer' and killed him. Never liked the guy, but he wasn't the one who was supposed to die that day. Just earlier today police found my note that had been sitting still for 27 years... However, I remember every letter I placed, every inch of me had been waiting for this day. It read:

Dear whoever finds this,

I'm dead now. You think you killed my murderer? Wrong. And if you don't find my murderer in a week I will kill everyone. Take my warning seriously, or you'll face the consequences of it. Go to the place I died before time is up and say my murderer's name three times, and I won't harm a soul.

P.S. - First clue is in my old foster home, where I used to live with my foster parents. Good luck.

Sincerely,

Jessica Rivertt
