I couldn't agree more! What made me think he has something to do with it is one of the phone calls from jail. She is talking to Christine/Christina and is asked if Tony had any involvement the way she answers is a dead give away. Something isn't right there IMO.
I'm not so sure. I was raised with "if you don't have something nice to say ... don't say it"! Some things are left better off not spoken. If he has been cooperative with LE; then that is all that should matter. He is not verbal with press, most likely because he regrets the day he met Ms. Casey.
I honestly don't think anyone is covering anything up for anyone ... the person responsible for this whole mess is sitting in a jail cell right now.
Her parents and brother are guilty of believing her lies and trying to help her. Tony and his friends are guilty of having the misfortune of having crossed paths with Casey. Same goes for Amy and all of Casey's other friends.
Casey is one messed up person.
