Siegfried Woelki’s disappearance on October 4, 1982, has left a void in the lives of those who knew him and a lingering question for the community of Hackettstown, New Jersey. On that Monday afternoon, around 5:30 p.m., Woelki, then 31, stopped at a Krauser's food store. He spoke with a friend who was working, mentioning that he had 'some business to attend to' and would be back at his apartment in a few hours. Later that evening, between 8:00 and 9:00 p.m., he called his father from the North Jersey Packing House in Long Valley, where he worked as a part-time butcher. He arranged to meet his father there the next day at 6:00 p.m. to wrap meat, a seemingly ordinary plan that would tragically never come to fruition.

The following day, the owner of the packing house arrived around 5:15 p.m. and noticed Woelki's car in the parking lot. The vehicle was unlocked, with the driver's side window partially down. Inside, the glove compartment, where Woelki typically kept his work keys, was open, but both his car keys and the packing house keys were gone. Despite the unlocked car, the packing house itself was securely locked and the alarm was set. When Siegfried failed to meet his father as planned, the police were notified at 8:00 p.m. on October 5th. An extensive search of his car, the packing house, and the surrounding grounds yielded no clues as to his whereabouts and showed no signs of a struggle.

The mystery of what happened to Siegfried Woelki has endured for decades. At the time he went missing, he was living with his long-time girlfriend at the Towpath Apartments in Hackettstown. Described as a white male with brown hair and brown eyes, standing about 5'9' and weighing around 190 pounds, he also wore glasses and had a fair complexion. Known by the nickname 'Sig,' he was a college wrestler in his younger years. Over the years, the North Jersey Packing House was demolished to make way for a park, and construction workers were vigilant for any signs of human remains, but nothing was ever found. The case eventually went cold and was handed over to the Morris County Prosecutor's Office. The overview of this case is one of a man who vanished after a series of mundane and seemingly non-threatening events, leaving behind his car and a trail of unanswered questions. With no evidence of foul play or a voluntary departure, the disappearance of Siegfried Woelki remains an unsolved and deeply felt loss for his family and community.
