Actually, Hunter being as mercenary as he is, maybe he can be flipped and convinced to rat out his family.
Offer to let him keep his shiny gun and license. Send a midget hooker with a gimp leg and Sailor Moon tats to broker the deal and ... Done!
GET REAL!!! Hunter will NEVER FLIP!! His FAMILY IS THICK AS THIEVES!! AND THEY ARE!! He is their BAG MAN!!
