Charles Robert Duke, 46, was last seen in Austin, Texas, on September 20, 2011. He is described as 5 feet tall, about 135 pounds, with brown hair. Few details surround his disappearance, and the absence of new evidence or leads has left the investigation cold.

The case remains listed on missing person databases, including the Texas Department of Public Safety and NamUs. The Austin Police Department’s Cold Case Unit handles long‑term missing person investigations and collaborates with other agencies, but there have been no significant reported breakthroughs in Duke’s case.

Anyone who knew Charles, saw him in Austin around September 2011, or has information that might help investigators is asked to come forward.
