I think they both know what happened, either because Misty or Tommy told them, or because they're not stupid, & they know their kids, & figured it out. I'm thinking Lisa may be a little more involved. On those tapes, Hank didn't act like a dad who was demanding answers. Normal parents would've beaten the answers out of them, before they all got busted. Where was the outrage? the pleading? the reasoning with Misty to come clean, in order to help herself? Early on, Hank made a point to say that Misty was his wildest child, & the boys were so much better. I thought that was mean & unnecessary then, (I would never put one child down while comparing her to another), & now I'm a little suspicious that he was defending his sons, because he suspected something. IDK what Timmy was up to, but Tommy had stolen a gun from a blind man, (WITH HIS DEAR OLD MOM)), had gotten into a physical fight with his dad, had gotten some kind of domestic charges filed involving Lindsey, had gotten busted at the bus stop, had committed home burglaries, had the neighbors talking about his odd behavior, had Misty accusing him of 'messing' with her, when she was younger, had Misty calling him a crackhead...& he's the good kid? I don't think so. & now we have Hank saying that he, himself, was on that fishing trip & heard Joe talking about dumping a body. again, I don't think so. It sounds like Hank, is once again, trying to muddy the waters & keep suspicion off of Tommy. Hank & Lisa went to Ron's hearing, IMO, because they were worried about Tommy being threatened with murder charges. They were just looking out for their boy. MOO. Also, I've said this before, but I think it bears repeating. Hank IMO, was very manipulative towards Misty, in a jail recording. In one breath, he was talking about moving, & in the next breath, (after getting Misty extremely upset), relayed the message from Tommy asking why she hated her brother. Misty, in tears, said 'I don't hate my brother'. This was right after , (paraphrasing here), Misty said, 'you guys aren't gonna come see me anymore?' & let me just say, that conversation made me furious, & made me like Hank, a lot less.
