A Tennessee Woman Suddenly Disappeared with Her 2-Year-Old Daughter Two Decades Ago. They're Still Missing.

A 2-year-old girl vanished along with her mother in Tennessee more than 20 years ago. The next day, her mother was reportedly seen one last time, though the infant was nowhere to be found.

The duo first disappeared when the mother's boyfriend dropped them off at a gas station on March 25, 2004 and claimed he saw them get into a white car. The next day, Joey Benton told police that the mother, Jennifer Wix, arrived back at his house without her daughter before leaving once again in the white car.

That is the last time either of them was accounted for. Adrianna Wix, Jennifer Wix's daughter, would be 22 years old now.

Benton, Jennifer Wix's boyfriend who lived in the Owens Chapel community of Cross Plains, Tennessee, at the time, has not been charged in connection with the case, according to WKRN.

“It’s not top of mind for a lot of people anymore, but it’s top of mind for us,” Casey Robinson, who was 15 at the time of her sister and niece's disappearance, told WKRN in 2021. “I can't stop thinking about it because they’re gone. Someone took them. Someone did something to them.”

“It was treated as a runaway case, then turned into missing persons. When nobody heard from her, the case later turned into a homicide case,” Robinson said.

NBC News recently reported that deputies have not been able to confirm Benton's story about the missing mother and daughter's final days.

According to the outlet, police have had no credible sightings of the mother and daughter over the past two decades, and there are currently no suspects in the missing persons case.

Robinson noted in 2021 that cases like her sister and niece's often "seem to get forgotten."

"I understand that there are more time sensitive cases right now," she said, "but what I’m asking is that you don’t forget them because something did happen to them in that town, at that home, with that family,"
