Joseph Robertson was 63 when he was last seen leaving the Dover Retirement Facility in Dover, New Jersey, on January 2, 2004. He walked away from the facility and was never heard from again; the circumstances of his departure reportedly offered no immediate cause for alarm but yielded no clear leads afterward.

He is described as a white male with graying hair and brown eyes, about 6 feet tall and 200 pounds. He had an allergy to penicillin and no known scars, marks, or tattoos that might help identify him. The Toms River Police Department and the New Jersey State Police Missing Persons Unit investigated, and his case has been classified as an endangered missing person.

What happened to Joseph after he left the retirement facility that January day, and who might have seen him or his car that afternoon?
