Dateline NBC “Chameleon” July 11 2026
Dateline NBC presents “Chameleon” as a Weekend Mystery on Saturday, July 11, 2026, at 9:00 p.m. ET/8:00 p.m. CT. Reported by Andrea Canning, the broadcast revisits the disturbing case of a New Jersey woman whose disappearance led investigators to uncover a husband’s hidden past—and the startling realization that another of his wives had also vanished years earlier.
The investigation centers on Frances “Fran” Smith, who disappeared from New Jersey, leaving her family desperate for answers. As days turned into weeks, those closest to Fran became increasingly suspicious of her husband, John Smith, believing his behavior after her disappearance was unusual. Rather than appearing frantic to locate his missing wife, relatives felt he showed little urgency or concern, prompting them to question whether they truly knew the man Fran had married.
As detectives dug deeper into John’s background, they uncovered a shocking revelation. Before marrying Fran, John had been married to another woman, Janice Hartman. Investigators soon discovered that Janice had also disappeared under mysterious circumstances years earlier. The similarities between the two cases transformed what initially appeared to be a missing persons investigation into a far more disturbing mystery involving a man with a carefully concealed past.
The episode examines how investigators pieced together decades of evidence while trying to determine whether the two disappearances were connected. As law enforcement revisited old records and interviewed family members, they uncovered a pattern of deception that raised new questions about John’s identity, his relationships, and the circumstances surrounding both women’s disappearances.
“Chameleon” features interviews with Fran Smith’s daughter and sister, who remember her as a devoted mother and supportive family member while reflecting on the decades-long search for answers. Detectives also discuss what they learned about Janice Hartman during the investigation and explain how discoveries from one missing person’s case ultimately helped advance another.
Andrea Canning’s report follows investigators as they unravel the hidden history of a man who appeared to reinvent himself while leaving tragedy in his wake. Through interviews with family members and law enforcement, “Chameleon” explores how persistence and renewed investigative efforts helped expose secrets that had remained buried for years.
