In the small community of Lock Haven, Pennsylvania, a young man's life took an uncertain turn on November 21, 2018. On that day, 17-year-old Diego Alonzo Perez, a male with black hair and brown eyes, was seen for the last time. Originally from Guatemala, Diego was in the 500 block of Woods Avenue when he vanished, leaving behind a void of information and a community searching for answers. Since that day, he has not been heard from again, and the details surrounding his disappearance have remained frustratingly scarce. The days following Diego's disappearance turned into weeks, then months, and now years, with no significant leads to illuminate what might have happened to him. His case is classified as an endangered missing person case, a designation that underscores the deep concern for his safety and well-being. In an effort to generate new leads as time has passed, an age-progressed photo showing what Diego might look like at 20 years old was circulated, a poignant reminder of the years that have slipped by since he was a teenager. Despite these efforts, the silence and lack of information have been a defining and challenging characteristic of his case. The investigation into Diego's disappearance remains with the Pennsylvania State Police. The passage of time has not diminished the hope of finding answers, but it has compounded the mystery. The overview of this case is one of profound uncertainty; a young man on the cusp of adulthood disappeared without a trace from a residential street. The lack of available details has left his loved ones and investigators with a painful puzzle, marked by an absence of clues and the enduring question of what happened to Diego Alonzo Perez.
