I’d still like to know on how they got caught.
They actually did seek help from the police more than once, Gascon is lying through his teeth.
The cops blew 'em off.
When the pimp got dead, Gascon simply assumed they had shoved incompetence in his face instead of taking a knee with "thank you, may I have another sir?"
So he searched all the phone records. He has date, time, location and number called but no transcripts, so he made up the scenario to fit.
