Summary based on the NamUs case record (MP40734) and 8 other sources
In the spring of 2017, the quiet life of 33-year-old Benjamin Howard Mosser was abruptly interrupted, leaving his family and friends with unanswered questions that linger to this day. A resident of Shiremanstown, Pennsylvania, a small community in Cumberland County, Ben, as he was known to his loved ones, was last seen on March 31, 2017. He was a recent graduate, having earned associate degrees in HVAC and mechanical engineering from Harrisburg Area Community College in December 2016, and was actively seeking employment in his new field. His disappearance became apparent when he failed to arrive for a planned dinner at his parents' home on April 2, 2017, an absence that was completely out of character for the reliable and family-oriented man.

The initial investigation into Ben's whereabouts quickly uncovered a series of perplexing clues at his apartment. While his vehicle was found parked in its usual spot, suggesting he hadn't traveled far by his own means, several personal items were missing. His wallet and cell phone were gone, yet his eyeglasses, which he regularly wore, were left behind. This detail struck investigators and his family as particularly odd, as it seemed unlikely he would have voluntarily left without them. Further adding to the mystery was the fact that there has been no publicly reported activity on his cell phone or bank accounts since his disappearance. Ben was described as a white male, 5'10' and weighing around 185 pounds, with black hair that he sometimes wore in a short ponytail, and brown eyes. He also had a thin beard and mustache and a distinctive large cross tattoo on the left side of his chest. Those who knew him mentioned his interest in knives and firearms and that he often wore a baseball cap.

As days turned into weeks and then years, the trail for Benjamin Mosser grew cold, with very little new information emerging in the public sphere. The Cumberland County District Attorney's Office CID Unit took on the case, but despite their efforts, no significant leads have been announced. Information about the investigation has been sparse, and there have been no named suspects or persons of interest. The case is a haunting example of how someone can vanish without a trace, leaving a void in the lives of those they left behind. The overview of the case reveals a young man on the cusp of a new chapter in his life, who disappeared under circumstances that are both mysterious and concerning. The combination of his missing personal effects, the items left behind, and the complete lack of communication since March 31, 2017, has created a painful and enduring mystery for his family and the community that continues to hope for answers.
