Lewis was last seen on September 25, 2003, entering Hamlin Beach State Park in New York, driving his 1987 Volkswagen van. A photograph of the van is posted below this case summary. Lewis, who is from San Francisco, California, was traveling the east coast at the time of his disappearance. He stayed in campgrounds in state parks. He has never been heard from again. On September 29, his van was found abandoned at Hamlin Beach State Park; the park authorities contacted police and reported Lewis's disappearance at this time.

Lewis enjoys doing extensive traveling and has lived in his van, which has a kitchen and sleeping area, for months at a time. He relies on a trust fund to support himself. His family says he kept to himself but it is uncharacteristic for him not to contact them for this long a time. His case remains unsolved.
