Summary based on the NamUs case record (MP54740) and 2 other sources
In the quiet, forested region of Amanda Park, Washington, a young man's presence seemingly vanished, leaving behind a void of information and decades of unanswered questions. Glenn Allen Tweten, a 23-year-old male, was last seen by his family in 1978. The exact date of his disappearance is unclear, though records indicate his last contact was around January 1st of that year. At the time he went missing, Glenn was described as a White/Caucasian male, standing at 5 feet 6 inches tall and weighing approximately 170 pounds. He had brown hair and brown eyes, and a distinguishing scar on the top of his right hand. The circumstances surrounding the day he was last seen are vague, with very little information available to the public or law enforcement about what might have transpired.

The years immediately following Glenn's disappearance are shrouded in silence. For reasons that are not publicly documented, his case was not officially reported to law enforcement until decades later. On January 16, 2019, the Kitsap County Sheriff's Office formally opened an investigation into the matter, giving it the case number K19-000583. This significant passage of time has undoubtedly complicated the efforts to uncover what happened to Glenn. Potential witnesses may have moved, their memories may have faded, and any physical evidence that might have existed at the time is likely long gone. The official record states simply and poignantly, 'Glenn has not been seen by family since 1978.'

The investigation into Glenn Allen Tweten's disappearance remains open. Despite the considerable challenges posed by the cold nature of the case, law enforcement continues to seek information that could shed light on his fate. The case is a reminder of the enduring pain and uncertainty that families of the missing face. Without any confirmed sightings or substantial leads, the narrative of Glenn's disappearance is one of profound mystery. It is a story marked by an absence of information, a family's long-held hope for answers, and the dedicated, albeit delayed, effort of investigators to piece together a puzzle that is now over four decades old. Anyone with information regarding Glenn's whereabouts or the circumstances of his disappearance is encouraged to contact the Kitsap County Sheriff's Office.
