FRANKLIN, Wis. (CBS 58) -- A Franklin woman who went missing nearly three years ago, is now one of the subjects of a new series tracking cases of missing people. 

The show on Paramount+ is called, "Never Seen Again," and season five -- which premiered on March 12 -- features the disappearance of Sandra Eckert. 

Eckert, a 70-year-old grandmother, was last seen March 26, 2021. At the time, her husband told police they had an argument. It ended with Eckert threatening divorce. 

Eckert's kids say their dad has made threats before, and there is still a $50,000 reward for information into her disappearance.
