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.
We are discussing the case of Shannon Paulk and invite you to join in on the conversation. Comment below with your thoughts, questions, and theories. Follow, like, and share to help extend the reach of her case. As long as we can keep her name and face visible, the more likely it is that it will end up in front of someone with a nudge for them to come forward with information that might just provide some answers.

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?

August 24, 2004. For most people in Waterbury, Connecticut, it was an ordinary summer day. But for the Smolinski family, it marked the beginning of a nightmare that has never ended. Thirty-one-year-old Billy Smolinski was making plans for the future. He was working, spending time with friends and family, and navigating changes in his personal life. According to those closest to him, he wasn't a man preparing to disappear. Yet sometime after telling a neighbor he would be away for a few days to check out a car he wanted to buy, Billy vanished without a trace. His truck was left behind. His wallet was left behind. His keys were left behind. Even his dog, Harley, whom he asked someone to watch, was never picked up. As the days passed, Billy's family became convinced that something terrible had happened. Investigators would eventually come to believe the same thing. Over the years, authorities searched forests, rivers, quarries, and remote properties. Witnesses were interviewed. Tips were chased across Connecticut. Potential suspects were scrutinized. New leads surfaced, only to lead investigators back to the same haunting question. What happened to Billy Smolinski? And how can a man seemingly vanish into thin air, leaving behind almost everything he owned? In this episode, we'll examine Billy's final known movements, the evidence investigators uncovered, the people who became central figures in the investigation, and the unanswered questions that continue to surround one of Connecticut's most enduring mysteries. This is the disappearance of William "Billy" Smolinski Jr.
