Dateline Missing in America - Ep. 30: No Ordinary Sunday

Marilyn “Niqui” McCown vanished from Richmond, Indiana, on July 22, 2001, just weeks before her wedding. The 28-year-old was last seen on security video at a convenience store near a local laundromat. Months later, the GMC Jimmy she had been driving was found in Dayton, Ohio; her laundry was found folded inside the vehicle. Dateline’s Josh Mankiewicz speaks with Niqui’s sister, Michelle McCown-Luster, and Niqui’s daughter, Payton Johnston, about their long search for answers. Josh also speaks with WDTN co-anchor Kelley King, who has followed Niqui’s case for years. Also featured is Richmond Police Department Detective Mike Wright, who continues to investigate Niqui’s disappearance. Niqui was 5’3” and weighed 115 pounds at the time of her disappearance with brown hair and eyes. She was last seen wearing a pink top, biker shorts, and sandals. She would be 53 years old today. Anyone with information about Niqui’s case is asked to call the Richmond Police Department at 765-983-7247.
