I looked up the significance of hanging in Judaism. In Wikipedia it mentioned that a hanged person is considered under a divine curse.

There is more information in the above link, and it is pointed out that
the body could not be left hanging overnight according to Jewish law. If the Shermans were killed Wed. night, and not found until Fri. a.m. as seems to be the case, then it seems the killers wanted to send a message about them being cursed and not worthy of dignity in death because of some insubordination, or crime. This goes very deep among extremely powerful people, in my opinion, and I doubt they will ever find the professional assassins, or those who ordered it. No wonder the children looked so frightened at the funeral. I also don't think it was an accident that Honey was murdered too. They could have waited until she left for Florida. For some reason a high level professional hit was put out on both of them, and the bodies left hanging on display as a message to others, not to cross these powerful people. I have no idea who they are, but it is likely that those who are supposed to get the message got it. I think this was a double murder staged as a double murder, and a curse besides. IMO
