On the evening of February 6, 2012, 18-year-old Robert Earl Sine, known as Bobby, left the care of his mother while in a severe mental health crisis. After a week without eating and four days without sleep, during which he had reported suicidal thoughts, Bobby had been taken to Skagit Valley Hospital’s emergency room but refused treatment. While his mother was driving him home, near the Division Street Bridge at about 9:30 p.m., he jumped from the moving car and ran toward the riverbank and boardwalk heading for Edgewater Park; that was the last confirmed sighting.

Searches of the area followed and a river search was conducted. Three weeks later his wallet was found near the river containing his Social Security card, identification, and money, which suggested robbery was not involved. He was described as likely to appear frightened or agitated if approached. At the time he vanished he had brown hair, blue eyes, a beard and mustache, and was wearing a white puffy hooded jacket with black markings, baggy blue jeans, and a black knit stocking hat.

What did anyone in Mount Vernon see that night or in the days after Bobby disappeared that might explain what happened to him?
