Season 4 - The Final Season Manway "Cal" Lam - Quincy, Massachusetts - Episode 82
Boston area business analyst, Manway Lam, who admitted to have a string of bad relationships, went to meet up with whom he believed was a 12-year old girl.
Manway met a fake child on Skout. The 'child' told him that she was masturbating. Invited Manway to join her. Manway was very careful with his text messages, as to not say anything incriminating or overly sexual.
During the confrontation Manway apologized for his behavior although claimed he did nothing wrong. He also said he'd deserve the father of the fake child beating him up for coming to meet with a 12-year old.
UPDATE (June 2020): We discovered Manway was convicted of rape of a 16-year old girl in 2005. He went to prison. The relationship was consensual but Manway flew multiple times to Idaho to sleep with a child he met online. He groomed the child so well, that shortly after he was released from prison (when the girl turned 18), she contacted and moved in with him. Their nearly 5-year relationship was rocky and filled with control issues. The woman (in her 30's now) said that she found a written letter from another girl, someone she thinks was 15-years old, while they were living together. In a followup interview, Manway complained of threats and bullying. He said that he had little support and couldn't tell us whether or not he had conditions to stay away from children.
