Robert Wayne Linder was a 24-year-old DePaul University business student from Arkansas when he vanished from Chicago in early summer 1969. On June 2 he finished a final exam and then went to a bank to withdraw money intended as a rent deposit for a new apartment. Those actions were consistent with plans to remain in the area, and they are the last confirmed things he did.

Linder was described as a white male, brown hair, blue eyes, 5 feet 9 inches and about 155 pounds. After leaving the bank he was never seen or heard from again; there has been no known contact, financial activity, or discovered remains. Few details are available about what happened after that day, and the investigation has yielded little information over the decades.

Did anyone in Chicago in 1969 have information about where Robert planned to live or whom he might have been with after leaving the bank?
