On an ordinary August morning in 2001, an eleven-year-old girl walked out her front door to play in her Alabama neighborhood — the way she had a hundred times before. She never came home. Two months later, hunters would find what was left of her in the woods fifteen miles away. Her name was Shannon Paulk. And more than two decades later, no one has answered for what happened to her.

In the early hours of May 1960, a metal box containing 25-30 sticks of dynamite exploded under the bedroom of Jethro and Mattie Green. Jethro was thrown from his bed into the yard, suffering minor injuries; their 17-month-old son, who was also in the room, was injured. Mattie Green did not survive. Sixty-six years later and we still don’t know who placed this bomb and why?

It was the summer of 1973, and 20 year old Donna Lemon was making the most of it like any true Montanan before the snow starts to fall again in just a few short months. The eldest of two daughters with an avid outdoorsman for a father, Donna was very active. She rock climbed with her father and went fishing, camping, skiing, sledding, snowmobiling, snowshoeing, and horseback riding. She had just attended the Ennis Rodeo on the 3rd and the 4th of July, and was supposed to meet with a friend at 4pm on the 5th to go horseback riding. She never arrived at her friend’s house. Her friend rang the alarm bell instantly and drove around looking for her, to no avail. Two days later, her green 1969 Ford Mustang would be spotted in a parking lot in Idaho Falls. Two days after that, her body would be discovered in the grass on the bank of the Snake River, approximately 1.5 miles from where her car was left. Family, friends, and officials all believed it had to be someone she knew. Over fifty years have passed since the tragic death of Donna Lemon and the question of who and why still linger. Do you have a piece of the puzzle?
