<human>: So, using Google tonight I just found out my step-father is/was a con man.  I have always thought something was not right about him, that his background seemed too fantastic to be real, but I never expected to find out he was actually pretty much a total lie.  I Googled him today after a conversation with my sister and found newspaper articles showing past arrests where he had fabricated a military career. He also was arrested for stealing money from a past girlfriend.  

I guess I want to know what I should do.  I shared the info with my husband and my siblings and we're all surprised, pissed.  The extent of the deep shit he fabricated - let me just say it was an elaborate lie.  I have know him almost 20 years and he's still trying to pass off the fake past to us.

For privacy I don't want to disclose any further details about it, but ...I just wanted to get some thoughts about whether I should confront him or my mother with this information. They have had the appearance of being happily married for years, but I suspect my mother is either in the dark, in denial, or worried that if she gets a divorce he would somehow do something bad like steal her retirement.

Give me a shortened version of the text
<bot>: My mother has been married to a man with a history of faking his ID and cheating women.  Do con men change?
