To put it simply, don't question your instincts. How many cases have we all been on? And how often do we collectively feel that something is OFF when it comes to funding and family motivations and behavior? I would say sometimes, but it's usually justified. It isn't like we aren't used to seeing how grieving families react in crisis. And how often do we support the victim's family? Almost always, unless there is significant reason not to, IMO. And finally, how often do we ever feel this disgusted over and over regarding the family's behavior? I've been reading WS for 7 yrs and haven't seen a circus such as this one yet (Casey Anthony comes close though!) The answers will come in time, and this will all make sense. The majority of us here feel that something isn't right within the family. Our differing opinions seem not to be regarding whether something is or isn't right, but rather, what exactly is causing this to be so wrong.
As a recent benchmark, look at Hannah Graham's family. Now look at AJ's.
