See No Evil

This documentary delves into the murder of Christopher Duncan, a man who vanished after leaving his San Antonio, Texas apartment in the early hours of a summer night. He never returned, and the investigation seeks to uncover the circumstances surrounding his death.

The programme Christopher Duncan is presented as a single‑episode installment. It falls under the episode genre and centres on a true‑crime investigation, offering a concise yet focused look at a single case. The core of the episode follows the unresolved homicide of Christopher Duncan, a man who lived in San Antonio, Texas. He stepped out of his flat one day and never made it back, prompting an inquiry that ultimately revealed he had been murdered. The narrative tracks the moment he left his apartment and the subsequent realisation that his disappearance was anything but ordinary. Throughout the broadcast, the story is built around the facts that Duncan’s last known location was his own home and that his failure to return set off a police investigation. The episode lays out the circumstances surrounding his final departure, highlighting how his absence triggered concerns and led authorities to treat the case as a murder rather than a simple missing‑person scenario. In its conclusion, the programme summarises the key points of the investigation, reiterating that the only concrete detail known is Duncan’s exit from his San Antonio residence and the grim discovery that he never came back alive. The episode therefore serves as a straightforward account of that singular, tragic event.
