In the autumn of 2014, a 59-year-old man named Harry James Kostick vanished from his home in Endicott, New York. The last confirmed contact anyone had with Harry was sometime in September of that year, although there were unconfirmed reports of family members having contact with him as late as October or November. After that, there was only silence. Concern grew as time passed with no word from the 6-foot-tall, 230-pound man with gray hair and blue eyes. The circumstances surrounding his disappearance were unsettling, and as the weeks turned into months, the hope of his safe return began to fade, replaced by a growing sense of dread. The investigation into Harry's disappearance took a dark turn when suspicion fell upon his own son, Shawn Kostick. In March of 2018, nearly four years after Harry was last seen, Shawn was charged with second-degree murder, first-degree manslaughter, and other offenses related to his father's case. Investigators pieced together a grim timeline, believing that Harry's life had ended at his own home on Lincoln Avenue sometime between the first of September and the third of October in 2014. Evidence emerged suggesting that following his father's death, Shawn had forged checks on Harry's bank account, totaling nearly three thousand dollars. The case against him was further strengthened by allegations that he had intimidated and threatened potential witnesses. As the trial for his father's murder loomed, Shawn Kostick, already incarcerated for an unrelated crime, chose to accept a plea deal in January 2020. He pleaded guilty to first-degree manslaughter, admitting that he had caused his father's death during a physical altercation where he intended to cause serious injury. In exchange for his plea, he was sentenced to ten years in prison. Despite this admission of guilt, a crucial piece of the puzzle remains missing. To this day, Harry James Kostick's body has not been recovered, and his son has not revealed its location. The case, while legally closed, leaves a lingering sense of incompletion for those who knew and loved Harry. The official classification of his case is that of an endangered missing person, but with his son's conviction, it is widely believed that foul play was involved in his disappearance. The lack of a final resting place for Harry continues to be a source of unresolved grief for his family and community.
