In the late summer of 2004, William 'Billy' Smolinski, Jr., a 31-year-old man from Waterbury, Connecticut, seemingly vanished. On August 24, he asked a neighbor to look after his beloved German Shepherd, Harley, for a few days, explaining he was heading north to look at a car. This was the last time he was seen. When he didn't return as planned, his family's concern grew. They found his truck parked at the end of his driveway, an unusual spot for it, and inside were his wallet and keys. Initially, law enforcement treated it as a case of a man who had left on his own, but his family knew this was completely out of character for the dependable and hardworking individual who held multiple jobs. Billy was known for his love of the outdoors, including fishing, hunting, and snowmobiling, and had a close relationship with his family.

As days turned into weeks with no word from Billy, and his bank accounts remained untouched, the theory that he had left voluntarily began to crumble, and the possibility of foul play emerged. The investigation into his disappearance would prove to be complex and frustrating for his loved ones. A significant turn in the case came when a man named Chad Hanson claimed that Smolinski had been murdered by Shaun Karpiuk and that he had helped bury the body. This information led investigators on several extensive and costly searches in various locations, including Seymour, Naugatuck State Forest, and Oxford, but all efforts to find Billy's remains were unsuccessful. The situation grew more complicated when Karpiuk died of a drug overdose in 2005, taking any potential direct knowledge of the events with him. Hanson was later charged and convicted of making false statements to the police, adding another layer of pain and confusion for the Smolinski family.

The years since Billy's disappearance have been marked by his family's unwavering determination to find answers and bring him home. They have faced immense challenges, including legal battles. The case has received significant media attention, and the family’s advocacy led to the passage of 'Billy's Law,' federal legislation aimed at improving the national databases for missing persons and unidentified remains. The investigation into William Smolinski Jr.'s disappearance has been long and arduous, involving multiple law enforcement agencies. While it is now widely believed that he was the victim of a homicide, his case remains officially unsolved. The lack of resolution has left a profound and lasting impact on his family and community, who continue to hope that one day the truth will come to light and they will finally have the answers they have sought for so long.
