His ex-wife's word. I've personally seen women in my life lie about various kinds of abuse, just to win custody or fuck over their ex, then brag about it to me and everyone that they're so clever using the system like that. This seems like more of the same.

Her story doesn't pass the smell test. "He forced me to go on Craigslist and fuck random dudes! He's the degenerate one!" Reading between the lines, you see that the police think her story is so bullshit, they don't even check her phone for the child porn photos or messages she claims he sent to her.
