In the quiet city of Mount Vernon, Washington, a young man's life took a distressing turn, leaving his family and community with years of unanswered questions. On the evening of February 6, 2012, 18-year-old Robert Earl Sine, known affectionately as Bobby, was in the midst of a severe mental health crisis. For a week he had not eaten, and for four days he had not slept, plagued by suicidal thoughts. His concerned mother had taken him to the Skagit Valley Hospital emergency room, but he refused treatment. While she was driving him home, at approximately 9:30 p.m., their car neared the Division Street Bridge. In a moment of distress, Bobby jumped from the moving vehicle and fled on foot, last seen near the riverbank and boardwalk, heading towards Edgewater Park.

The immediate aftermath of Bobby's disappearance was filled with frantic searching and a profound sense of worry. Given his fragile mental state at the time he vanished, he was considered to be at high risk. Authorities and loved ones scoured the area, but their efforts yielded only one clue. Three weeks after he was last seen, Bobby's wallet was discovered near the river. Inside were his Social Security card, identification, and money, leaving more questions than answers. A search of the river was conducted, but it did not lead to any further discoveries. The presence of his intact wallet suggested that robbery was not a motive in his disappearance.

Years have passed since Robert Sine was last seen, yet his case remains an open and haunting mystery for the Mount Vernon community. He is described as a kind individual who may appear frightened or agitated if approached. At the time of his disappearance, he had brown hair, blue eyes, and a beard and mustache. He was last seen wearing a white puffy hooded jacket with black markings, baggy blue jeans, and a black knit stocking hat. The circumstances surrounding that February night—his severe psychotic episode and his sudden flight—paint a tragic picture of a young man in deep distress. The discovery of his wallet offers a small but incomplete piece of the puzzle, leaving his family to wonder what happened after he ran from the car. The lack of resolution continues to weigh heavily on those who know and love him, as they hold out hope for answers in the disappearance of Bobby Sine.
