(FOX NEWS) - Billy Smolinski was 31 and in love when he disappeared nearly 12 years ago from his Connecticut home -- a one-story house in Waterbury not far from the farm where his parents had raised him.
Since that day -- Aug. 24, 2004 -- no one has seen or heard from Billy, the only son of William and Janice Smolinski -- a hard-working tow-truck driver who, by all accounts, loved sports, his German Shepherd "Harley," and his close-knit family.
Detectives have long suspected foul play, according to sources close to the investigation, but without a body or other forensic evidence, the case is a mystery that continues to haunt Connecticut residents. Yet with each passing year, the family's determination to solve the case never wavers and, as the 12th anniversary of his disappearance nears, they are appealing to the public for information.
"Someone, somewhere knows something," said Janice Smolinski.
"He just loved life," said Smolinski, who believes her son was murdered. "He had such a future ahead of him."
