Once Johnathan Walton learned of the extent of Marianne Smyth's deception, he wanted to prosecute her to the fullest extent of the law. In early 2018, she was arrested.

During the trial, Smyth's legal team argued that Walton was motivated to go after her because he wanted to make a documentary about her. 

In January of 2019, Smyth was sentenced to five years in prison for scamming Johnathan Walton out of over $91,000. She is currently serving time at the Century Regional Detention Center in Los Angeles. 

The Con airs on Wednesdays at 10 p.m. ET on ABC.
